       .Synopsis
         Adds contitional formatting to worksheet.
+      .Description
+        Conditional formatting allows excel to
+        * Mark cells with Icons depending on their value
+        * Show a databar whose length indicates the value or a 2 or 3 color scale where the color indicate the relative value
+        * Change the color, font, or number format of cells which meet given criteria
+        Add-ConditionalFormatting allows these to be set; for fine tuning of the rules you can use the -PassThru switch,
+        which will return the rule so that you can modify things which are specific to that type of rule,
+        for example the values which correspond to each icon in an Icon set.
       .Example
-        $excel = $avdata | Export-Excel -Path (Join-path $FilePath "\Machines.XLSX" ) -WorksheetName "Server Anti-Virus" -AutoSize -FreezeTopRow -AutoFilter -PassThru

         Here Export-Excel is called with the -passThru parameter so the Excel Package object is stored in $Excel

         Finally the workbook is saved and the Excel object closed.

-        C:\> $r = Add-ConditionalFormatting -WorkSheet $excel.Workbook.Worksheets[1] -Range "B1:B100" -ThreeIconsSet Flags -Passthru
-        C:\> $r.Reverse = $true ;   $r.Icon1.Type = "Num"; $r.Icon2.Type = "Num" ; $r.Icon2.value = 100 ; $r.Icon3.type = "Num" ;$r.Icon3.value = 1000

-        Again Export excel has been called with -passthru leaving a package object in $Excel
+        Again Export-Excel has been called with -passthru leaving a package object in $Excel
         This time B1:B100 has been conditionally formatted with 3 icons, using the flags icon set.
         Add-ConditionalFormatting does not provide access to every option in the formatting rule, so passthru has been used and the
         rule is to apply the flags in reverse order, and boundaries for the number which will set the split are set to 100 and 1000
+      .Example
+        Add-ConditionalFormatting -WorkSheet $sheet -Range "D2:D1048576" -DataBarColor Red
+
+        This time $sheet holds an ExcelWorkseet object and databars are add to all of column D except for the tip row.
+      .Example
+        Add-ConditionalFormatting -Address $worksheet.cells["FinishPosition"] -RuleType Equal    -ConditionValue 1 -ForeGroundColor Purple -Bold -Priority 1 -StopIfTrue
+
+        In this example a named range is used to select the cells where the formula should apply. If a cell in the "FinishPosition" range is 1, then the text is turned to puple, boldface.
+        This rule is move to first in the priority list, and where cells have a value of 1, no other rules will be processed.

+    Returns an Excel Package Object for the specified XLSX file
+.Description
+    Import-Excel and Export-Excel open an Excel file, carry out their tasks and close it again.
+    Sometimes it is necessary to open a file and do other work on it. Open-Excel package allows the file to be opened for these tasks.
+    It takes a KillExcel switch to make sure Excel is not holding the file open; a password parameter for existing protected files,
+    and a create switch to set-up a new file if no file already exists.
 .Example
-    $excel  = Open-ExcelPackage -path $xlPath
+    >
+    PS> $excel = Open-ExcelPackage -Path "$env:TEMP\test99.xlsx" -Create
+    $ws = Add-WorkSheet -ExcelPackage $excel
+
+   This will create a new file in the temp folder if it doesn't already exist. It then adds a worksheet -
+   because no name is specified it will use the default name of "Sheet1"
+.Example
+     >
+    PS>     $excel  = Open-ExcelPackage -path "$xlPath" -Password $password
     $sheet1 = $excel.Workbook.Worksheets["sheet1"]
-    Set-Format -Address $sheet1.Cells["E1:S1048576"], $sheet1.Cells["V1:V1048576"]  -NFormat ([cultureinfo]::CurrentCulture.DateTimeFormat.ShortDatePattern)

     Close-ExcelPackage $excel -Show
 
-   This will open the file at $xlPath, select sheet1 apply formatting to two blocks of the sheet and save the package, and launch it in Excel.
+   This will open the password protected file at $xlPath using the password stored in $Password.
+   Sheet1 is selected and formatting applied to two blocks of the sheet; then the file is and saved and loaded into Excel.

+        Creates Pivot table definitons for Export-Excel
+      .Description
+        Export-Excel allows a single Pivot table to be defined using the parameters -IncludePivotTable, -PivotColumns -PivotRows,
+        =PivotData, -PivotFilter, -PivotTotals, -PivotDataToColumn, -IncludePivotChart and -ChartType.
+        Its -PivotTableDefintion paramater allows multiple pivot tables to be defined, with additional parameters.
+        New-PivotTableDefinition is a convenient way to build these definitions.
+      .Example
+        >
+        PS>   $pt  = New-PivotTableDefinition -PivotTableName "PT1" -SourceWorkSheet "Sheet1" -PivotRows "Status"  -PivotData @{Status='Count' } -PivotFilter 'StartType' -IncludePivotChart  -ChartType BarClustered3D
+        $Pt += New-PivotTableDefinition -PivotTableName "PT2" -SourceWorkSheet "Sheet2" -PivotRows "Company" -PivotData @{Company='Count'} -IncludePivotChart  -ChartType PieExploded3D  -ShowPercent -ChartTitle "Breakdown of processes by company"
+        Get-Service | Select-Object    -Property Status,Name,DisplayName,StartType | Export-Excel -Path .\test.xlsx -AutoSize
+        Get-Process | Select-Object    -Property Name,Company,Handles,CPU,VM       | Export-Excel -Path .\test.xlsx -AutoSize -WorksheetName 'sheet2'
+        $excel = Export-Excel -Path .\test.xlsx -PivotTableDefinition $pt -Show
+
+        This is a re-work of one of the examples in Export-Excel - instead of writing out the pivot definition hash table it is built by calling New-PivotTableDefinition.

-# What's new to Aug 2018
+
+# What's new in Release 5.3
+
+- Help improvements and tidying up of examples and extra examples
+- Open-Excel Package and Add-Worksheet now add worksheets as script properties so `$Excel = Open-ExcelPackage -path test.xlsx ; $excel.sheet1` will return the sheet named "sheet1" `$Excel.SheetName` is a script property which is defined as `$this.workbook.worksheets["Sheetname"]`
+- Renamed Set-Column to `Set-ExcelColumn`, Set-Row to `Set-ExcelRow`, and Set-Format, to `Set-ExcelRange`. Added aliases so the old names still work.
+- `Set-ExcelRange` (or set-Format) used "Address" and "Range" incorrectly. There is now a single parameter `-Range`, with an alias of "Address".  If the worksheet parameter is present, the function accepts a string specifying cells ("A1:Z10") or a the name of range. Without the worksheet it accepts an object representing a named range or a Table; or a tables's address, or part of the worksheet.cells collection.
+- `Add-ConditionalFormatting`: Used "address" correctly, and it will accept ranges in the address parameter (range is now an alias for address). It now wraps conditional value strings in quotes when needed (for = <= >= operations string needs to be in double quotes see issue #424). Parameter intellisense has been improved. There are new parameters: `-StopIfTrue` and `-Priority` and support for using the `-Reverse` parameter with Color-scale rules (issue #430).  Booleans in the sheet are now supported as the value for a condition. Also brought the two different kinds of condition together inside Export-Excel, and fixed a bug where named-ranges didn't work in some places. In `New-ConditionalText`, more types of conditional format are supported, and the argument completer for -ConditionalTextColor was missing and has been added.
+- Improved handling of hyperlinks in `Export-Excel` (see issue #426)s
+- `Export-Excel` has better checking of Table and PivotTable names (for uniqueness) and a new test in quick charts that there is suitable data for charting. It also accepts hash tables for chart, pivot table and conditional formatting parameters which are splatted into the functions which add these.
+- Moved logic for adding a named-range out of Export-Excel and into a new function named `Add-ExcelName`, and logic for adding a table into a function named `Add-ExcelTable`; this is to make it easier to do these things independently of Export-Excel, but minimize duplication. The Add-ExcelTable command has extra parameters to toggle the options from table tools toolbar (show totals etc.) and set options in the totals row.
+- Moved PivotTable Functions out of Export-Excel.PS1 into their own file and moved Add-ExcelChart out of Export-Excel.ps1 into New-ExcelChart.ps1
+- Fixed bug in Merge-MultipleSheets  where background pattern was set to None, making background color invisible.
+- Fixed issues where formatting could be reset when using Export-Excel to manipulate an existing sheet without appending data; this applied to number-formats and tables.
+- `Add-PivotTable` has some new parameters `-PassThru` returns the pivot table (e.g. to allow names /sort orders of data series to be tweaked )  `-Address`  allows Pivot to be placed on an existing sheet; `-PivotTableStyle` allows a change from "Medium6", `-PivotNumberFormat` formats data cells. It is more flexible about how the source data is specified - copying the range options in Set-ExcelRange. `Add-ExcelChart` is now used for creating PivotCharts, and `-PivotChartDefinition`  allows a definition created with `New-ExcelChartDefinition` to be used when setting up a PivotTable. This opens up all the things that Add-ExcelChart can do without duplicating the parameters on Add-Pivot table and Export-Excel.  Definition, TableStyle, Numberformat and ChartDefiniton can be used in `New-PivotTableDefinition` .
+- `Add-ExcelChart` now supports -PassThru to return the chart for tweaking after creation; there is now a -PivotTable parameter to allow Add-PivotTable to call the code in Add-ExcelChart. And in `New-ExcelChartDefinition` Legend parameters (for size, bold & position ) are now supported
+- ChartDefinition and conditional formatting parameters can now be hashtables - anything that splats  Add-ExcelChart or Add-ConditionalFormatting, it should be acceptable as a definition.
+
+
+# What's new in Release 5.2
+- Value does not need to be mandatory in Set-Row or Set-Column, also tidied their parameters a little.
+- Added support for array formulas in Set-Format (it really should be set range now that it sets values, formulas and hyperlinks - that can go on the to-do list )
+- Fixed a bug with -Append in Export-Excel which caused it to overwrite the last row if the new data was a simple type.
+- NumberFormat in Export-Excel now sets the default for on a new / blank sheet; but [still] sets individual cells when adding to a sheet
+- Added support for timespans in Export excel ; set as elapsed hours, mins, secs [h]:mm:sss
+- In Export-Excel improved the catch-all handler for insuring values to cope better with nested objects (#419) and reduce the number of parse operations
+- Added -Calculate switch to Export-Excel and Close-Excel Package; EPPlus needs formulas to OMIT the leading = sign so where formula is set it now strips a leading = sign
+- Added -PivotTotals parameter where there was already -NoTotalsInPivot new one allows None, Both, Rows, Columns. (#415)
+- When appending Export-Excel only extended tables and ranges if they were explicitly specified. It now does it automatically.
+- Compare and Merge worksheet originally had a problem with > 26 columns, I fixed merge turns out I hadn't fixed compare ... I have now
+- Fixed bug where Export-Excel would not recognize it had to set  $TitleFillPattern - made the default 'Solid'
+- ExcludeProperty in Export-Excel now supports wildcards.
+- Added DateTime to the list of types which can be exported as single column.
+- Added Password support to Open- and Close-ExcelPackage (password was not doing anything in Export-Excel)
+- Gave Expand-NumberFormat a better grasp of currency layouts - it follows .NET which is not always the same as Excel would set:-(
+
+# What's new in Release 5.1.1
 - Set-Row and Set-Column will now create hyperlinks and insert dates correctly
 - Import-Excel now has an argument completer for Worksheet name - this can be slow on large files
 - The NumberFormat parameter (in Export-Excel, Set-Row, Set-Column, Set-Format and Add-ConditionalFormat) and X&YAxisNumberFormat parameters (in New-ExcelChartDefinition and Add-ExcelChart) now have an argument completer and the names Currency, Number, Percentage, Scientific, Fraction, Short Date ,Short time,Long time, Date-Time and Text will be converted to the correct Excel formatting strings.
 - Added new function Select-Worksheet to make a named sheet active: Added -Activate switch to Add-Worksheet, to make current sheet active, Export-Excel and Add-PivotTable support -Activate and pass it to Add-Worksheet, and New-PivotTableDefinition allows it to be part of the Pivot TableDefinition.
 - Fixed a bug in Set-Format which caused -Hidden not to work
+- Made the same changes to Add-Conditional format as set format so -switch:$false is processed, and 0 enums and values are processed correctly
+- In Export-Excel, wrapped calls to Add-CellValue in a try catch so a value which causes an issue doesn't crash the whole export but generates a warning instead (#410) .
 - Additional tests.

-        Set-Column takes a value which is either string containing a value or formula or a scriptblock
+        Set-ExcelColumn takes a value which is either a string containing a value or formula or a scriptblock

-        A column name can be specified and the new column can be made a named range.
-        The column can be formatted.
-      .Example
-        C:> Set-Column -Worksheet $ws -Heading "WinsToFastLaps"  -Value {"=E$row/C$row"} -Column 7 -AutoSize -AutoNameRange
+        A column heading can be specified and the new column can be made a named range.
+        The column can be formatted in the same operation.
+      .EXAMPLE
+        Set-ExcelColumn -Worksheet $ws -Column 5 -NumberFormat 'Currency'
+
+        $ws contains a worksheet object - and column E is set to use the local currecy format.
+        Intelisense will complete predefined number formats. You can see how currency is interpreted on the local computer with the command

+      .EXAMPLE
+        Set-ExcelColumn -Worksheet $ws -Heading "WinsToFastLaps"  -Value {"=E$row/C$row"} -Column 7 -AutoSize -AutoNameRange
+
         Here $WS already contains a worksheet which contains counts of races won and fastest laps recorded by racing drivers (in columns C and E)
-        Set-Column specifies that Column 7 should have a heading of "WinsToFastLaps" and the data cells should contain =E2/C2 , =E3/C3
+         Set-ExcelColumn specifies that Column 7 should have a heading of "WinsToFastLaps" and the data cells should contain =E2/C2 , =E3/C3 etc
         the data cells should become a named range, which will also be "WinsToFastLaps" the column width will be set automatically
+      .EXAMPLE
+        Set-ExcelColumn -Worksheet $ws -Heading "Link" -Value {"https://en.wikipedia.org" + $worksheet.cells["B$Row"].value  }  -AutoSize
+
+        In this example, the worksheet in $ws has partial links to wikipedia pages in column B.
+        The Value parameter is is a script block and it outputs a string which begins https... and ends with the value of cell at column B in the current row.
+        When given a valid URI,  Set-ExcelColumn makes it a hyperlink. The column will be autosized to fit the links.

       .Synopsis
-        Fills values into a [new] row in an Excel spreadsheet. To format a row without setting values, use Set-Format.
+        Fills values into a [new] row in an Excel spreadsheet. And sets row formmats.
       .Description
-        Set-Row accepts either a Worksheet object or an Excel package object returned by Export-Excel and the name of a sheet,
+         Set-ExcelRow accepts either a Worksheet object or an Excel package object returned by Export-Excel and the name of a sheet,
         and inserts the chosen contents into a row of the sheet.
         The contents can be a constant "42" , a formula or a script block which is converted into a constant or formula.
-        The first cell of the row can optional be given a heading.
+        The first cell of the row can optionally be given a heading.
       .Example
-        Set-row -Worksheet $ws -Heading Total -Value {"=sum($columnName`2:$columnName$endrow)" }
+         Set-ExcelRow -Worksheet $ws -Heading Total -Value {"=sum($columnName`2:$columnName$endrow)" }
 
-        $Ws contains a worksheet object, and no Row number is specified so Set-Row will select the next row after the end of the data in the sheet
+        $Ws contains a worksheet object, and no Row number is specified so  Set-ExcelRow will select the next row after the end of the data in the sheet
         The first cell will contain "Total", and each other cell will contain
             =Sum(xx2:xx99)  - where xx is the column name, and 99 is the last row of data.
             Note the use of `2 to Prevent 2 becoming part of the variable "ColumnName"
         The script block can use $row, $column, $ColumnName, $startRow/Column $endRow/Column
+      .Example
+        Set-ExcelRow -Worksheet $ws -Heading Total -HeadingBold -Value {"=sum($columnName`2:$columnName$endrow)" } -NumberFormat 'Currency' -StartColumn 2 -Bold -BorderTop Double -BorderBottom Thin
+
+        This builds on the previous example, but this time the label "Total" appears in column 2 and the formula fills from column 3 onwards;
+        the formula and heading are set in bold face, and the formula is formatted for the local currency,
+        and given a double line border above and single line border below.

+Function Set-ExcelRange {
+    <#
+      .SYNOPSIS
+        Applies Number, font, alignment and colour formatting, values or formulas to a range of Excel Cells
+      .DESCRIPTION
+        Set-ExcelRange was created to set the style elements for a range of cells, this includes autosizing and hiding, setting
+        font elements (Name, Size, Bold, Italic, Underline & UnderlineStyle and Subscript & SuperScript), font and background colors,
+        borders, text wrapping, rotation, aliginment within cells, and number format. It was orignally named "Set-ExcelRange"
+        It has been extended to set Values, Formulas and set ArrayFormulas (sometimes called Ctrl-shift-Enter [CSE] formulas); because of this
+        the name has become Set-ExcelRange - but the old name of Set-Format is preserved as an alias name may swapped.
+      .EXAMPLE
+        $sheet.Column(3) | Set-ExcelRange -HorizontalAlignment Right -NumberFormat "#,###" -AutoFit
 
-#>
+        Selects column 3 from a sheet object (within a workbook object, which is a child of the ExcelPackage object) and passes it to Set-ExcelRange
+         which formats as an integer with comma seperated groups, aligns it right, and auto-fits the column to the contents.
+      .EXAMPLE
+        Set-ExcelRange -Range $sheet.Cells["E1:H1048576"]  -HorizontalAlignment Right -NumberFormat "#,###"
+
+        Instead of piping the address in this version specifies a block of cells and applies similar formatting
+      .EXAMPLE
+        Set-ExcelRange $excel.Workbook.Worksheets[1].Tables["Processes"] -Italic
+
+        This time instead of specifying a range of cells, a table is selected by name and formatted as italic.

+      .SYNOPSIS
+        Converts short names for Number formats to the formatting strings used in Excel
+      .DESCRIPTION
+        Where you can type a number format you can write, for example 'Short-Date' and the module will translate it into the format string used by excel
+        Some formats, like Short-Date change how they are presented when Excel loads. (So date will use the local ordering of year, month and Day)
+        Other formats change how they appear when loaded with different cultures (depending on the country "," or "." or " " may be the thousand seperator
+        although excel always stores it as ",")
+      .EXAMPLE
+        Expand-NumberFormat percentage
+
+        Returns "0.00%"
+      .EXAMPLE
+        Expand-NumberFormat Currency
+
+        Returns the currency format specified in the local regional settings. This may not be the same as Excel uses
+        The regional settings set the currency symbol and then whether it is before or after the number and seperated with a space or not;
+        for negative numbers the number by wrapped in parentheses or a - sign might appear before or after the number and symbol.
+        So this returns $#,##0.00;($#,##0.00) for English US, #,##0.00 €;€#,##0.00- for French. (Note some Eurozone countries write €1,23 and others 1,23€ )
+        In French the decimal point will be rendered as a "," and the thousand seperator as a space.
