+Function Add-ExcelDataValidationRule {
+    <#
+      .Synopsis
+        Adds data validation to a range of cells
+      .Example
+        >
+        >Add-ExcelDataValidationRule -WorkSheet $PlanSheet -Range 'E2:E1001' -ValidationType Integer -Operator between -Value 0 -Value2 100 `
+             -ShowErrorMessage -ErrorStyle stop -ErrorTitle 'Invalid Data' -ErrorBody 'Percentage must be a whole number between 0 and 100'
+
+        This defines a validation rule on cells E2-E1001; it is an integer rule and requires a number between 0 and 100
+        If a value is input with a fraction, negative number, or positive number > 100 a stop dialog box appears.
+      .Example
+        >
+        >Add-ExcelDataValidationRule -WorkSheet $PlanSheet -Range 'B2:B1001' -ValidationType List  -Formula 'values!$a$2:$a$1000'
+               -ShowErrorMessage -ErrorStyle stop -ErrorTitle 'Invalid Data' -ErrorBody 'You must select an item from the list'
+        This defines a list rule on Cells B2:1001, and the posible values are in a sheet named "values" at cells A2 to A1000
+        Blank cells in this range are ignored. If $ signs are left out of the fomrmula B2 would be checked against A2-A1000
+        B3, against A3-A1001, B4 against A4-A1002 up to B1001 beng checked against A1001-A1999
+       .Example
+       >
+       >Add-ExcelDataValidationRule -WorkSheet $PlanSheet -Range 'I2:N1001' -ValidationType List    -ValueSet @('yes','YES','Yes')
+               -ShowErrorMessage -ErrorStyle stop -ErrorTitle 'Invalid Data' -ErrorBody "Select Yes or leave blank for no"
+        Similar to the previous example but this time provides a value set; Excel comparisons are case sesnsitive, hence 3 versions of Yes.

+## Start-Demo.ps1
+##################################################################################################
+## This is an overhaul of Jeffrey Snover's original Start-Demo script by Joel "Jaykul" Bennett
+##
+## I've switched it to using ReadKey instead of ReadLine (you don't have to hit Enter each time)
+## As a result, I've changed the names and keys for a lot of the operations, so that they make 
+## sense with only a single letter to tell them apart (sorry if you had them memorized).
+##
+## I've also been adding features as I come across needs for them, and you'll contribute your 
+## improvements back to the PowerShell Script repository as well.
+##################################################################################################
+## Revision History (version 3.3)
+## 3.3.3 Fixed:    Script no longer says "unrecognized key" when you hit shift or ctrl, etc.
+##       Fixed:    Blank lines in script were showing as errors (now printed like comments)
+## 3.3.2 Fixed:    Changed the "x" to match the "a" in the help text
+## 3.3.1 Fixed:    Added a missing bracket in the script
+## 3.3 - Added:    Added a "Clear Screen" option
+##     - Added:    Added a "Rewind" function (which I'm not using much)
+## 3.2 - Fixed:    Put back the trap { continue; }
+## 3.1 - Fixed:    No Output when invoking Get-Member (and other cmdlets like it???)
+## 3.0 - Fixed:    Commands which set a variable, like: $files = ls
+##     - Fixed:    Default action doesn't continue
+##     - Changed:  Use ReadKey instead of ReadLine
+##     - Changed:  Modified the option prompts (sorry if you had them memorized)
+##     - Changed:  Various time and duration strings have better formatting
+##     - Enhance:  Colors are settable: prompt, command, comment
+##     - Added:    NoPauseAfterExecute switch removes the extra pause
+##                 If you set this, the next command will be displayed immediately
+##     - Added:    Auto Execute mode (FullAuto switch) runs the rest of the script
+##                 at an automatic speed set by the AutoSpeed parameter (or manually)
+##     - Added:    Automatically append an empty line to the end of the demo script
+##                 so you have a chance to "go back" after the last line of you demo

-
-              .DESCRIPTION
-                DateTime objects are always converted to a short DateTime format in Excel. When Excel loads the file,
-                it applies the local format for dates. And formulas are always saved as formulas. URIs are set as hyperlinks in the file.
-
-                Numerical values will be converted to numbers as defined in the regional settings of the local
-                system. In case the parameter 'NoNumberConversion' is used, we don't convert to number and leave
-                the value 'as is'. In case of conversion failure, we also leave the value 'as is'.

-# What's new 5.4
+# What's new 6.0.0
+
+Thank you to [James O'Neill](https://github.com/jhoneill) for the optimizations, and refactoring leading to a ***~10x*** speed increase. Thanks to [ili101](https://github.com/ili101) for earlier PRs that provided the ground work for this.
+
+* Performance improvement to `Export-Excel` see [#506](https://github.com/dfinke/ImportExcel/issues/506) and [#555](https://github.com/dfinke/ImportExcel/issues/555). This has meant taking code in Add-CellValue back into process block of `Export-Excel`, as the overhead of calling the function was a lot greater than time executing the code inside it. [Blog post to follow](https://jamesone111.wordpress.com/). Some tests are showing a ***~10x*** speed increase. [#572](https://github.com/dfinke/ImportExcel/issues/572) was about a broken #region tag in this part of the code and that has been cleaned up in the process.
+
+* `Export-Excel` now has an -InputObject parameter (this was previously -TargetData , which is now an alias for InputObject).
+If the `inputobject` is an array, each item will be inserted, so you can run `export-excel -inputobject $x` rather than `$x | Export-Excel`, and if it is a `system.data.datatable` object it will be inserted directly rather than cell-by-cell. `Send-SQLDataToExcel` takes advantage of this new functionality. There are simple tests for these new items
+
+* `Export-Excel` previously assumed `-Now` if there were no other parameters, it will now assume `-Now` if there is no `-Path` or `-ExcelPackage`.
+The .PSD1 file now itemizes the items exported by the module [#557](https://github.com/dfinke/ImportExcel/issues/557)
+
+# What's new 5.4.5
+
+Thank you to [James O'Neill](https://github.com/jhoneill) for the great additions.
+
+- Modified Send-SQLDataToExcel so it creates tables and ranges itself; previously it relied on export-excel to do this which cause problems when adding data to an existing sheet (#555)
+- Added new command Add-ExcelDataValidation which will apply different data-validation rules to ranges of cells
+- Changed the export behavior so that (1) attempts to convert to a number only apply if the the value was a string; (2) Nulls are no longer converted to an empty string (3) there is a specific check for URIs and not just text which is a valid URI. Using UNC names in hyperlinks remains problematic.
+- Changed the behavior of AutoSize in export excel so it only applies to the exported columns. Previously if something was exported next to pre-existing data, AutoSize would resize the whole sheet, potentially undoing things which had been set on the earlier data. If anyone relied on this behavior they will need to explicitly tell the sheet to auto size with $sheet.cells.autofitColumns. (where $sheet points to the sheet, it might be $ExcelPackage.Workbook.Worksheets['Name'])
+- In Compare-Worksheet,the Key for comparing the sheets can now be written as a hash table with an expression - it is used with a Group-Object command so if it is valid in Group-Object it should be accepted; this allows the creation of composite keys when data being compared doesn't have a column which uniquely identifies rows.
+-  In Set-ExcelRange , added a 'Locked' option equivalent to the checkbox on the Protection Tab of the format cells dialog box in Excel.
+- Created a Set-WorksheetProtection function. This gives the same options the protection dialog in Excel but is 0.9 release at the moment.
+
+## New Example
+
+- Added [MutipleValidations.ps1](https://github.com/dfinke/ImportExcel/blob/master/Examples/ExcelDataValidation/MutipleValidations.ps1). Culled from the `tests`.
+
+# What's new 5.4.4
+
+- Fix issue when only a single property is piped into Export-Excel
+- Fix issue in `Copy-ExcelWorksheet`, close the `$Stream`
+
+# What's new 5.4.3
+
+- Added Remove-Worksheet: Removes one or more worksheets from one or more workbooks
+
+# What's new 5.4.2
+
+- Added parameters -GroupDateRow and -GroupDatePart & -GroupNumericRow, -GroupNumericMin, -GroupNumericMax and -GroupNumericInterval
+  to Add-PivotTable and New-PivotTableDefinition. The date ones gather dates of the same year and/or quarter and/or month and/or day etc.
+  the number ones group numbers into bands, starting at Min, and going up steps specified by Interval. Added tests and help for these.
+- Set-ExcelRow and Set-ExcelColumn now check that the worksheet name they passed exists in the workbook.

+      .PARAMETER DataTable
+        A System.Data.DataTable object containing the data to be inserted into the spreadsheet without running a query.
+        This remains supported to avoid breaking older scripts, but if you have a DataTable object you can pass the it
+        into Export-Excel using -InputObject.
       .EXAMPLE
         C:\> Send-SQLDataToExcel -MsSQLserver -Connection localhost -SQL  "select name,type,type_desc from [master].[sys].[all_objects]" -Path .\temp.xlsx -WorkSheetname master -AutoSize -FreezeTopRow -AutoFilter -BoldTopRow
 
         Connects to the local SQL server and selects 3 columns from [Sys].[all_objects] and exports then to a sheet named master with some basic header management
       .EXAMPLE
+        C:\> $dbPath = 'C:\Users\James\Documents\Database1.accdb'
+        C:\> $Connection = "Driver={Microsoft Access Driver (*.mdb, *.accdb)};Dbq=$dbPath;"

-        C:\> $Connection = ' Driver={Microsoft Access Driver (*.mdb, *.accdb)};Dbq=C:\Users\James\Documents\Database1.accdb;'
 
         C:\> Send-SQLDataToExcel -Connection  $connection -SQL $sql -path .\demo1.xlsx -WorkSheetname "Sizes" -AutoSize
 
-         This declares a SQL statement and creates an  ODBC connection string to read from an Access file and extracts data from it and sends it to a new worksheet
+        This creates an  ODBC connection string to read from an Access file and a SQL Statement to extracts data from it,
+        and sends the resulting data to a new worksheet
 
       .EXAMPLE
-        C:\> $SQL="SELECT top 25 DriverName, Count(RaceDate) as Races, Count(Win) as Wins, Count(Pole) as Poles, Count(FastestLap) as Fastlaps FROM Results GROUP BY DriverName ORDER BY (count(win)) DESC"
-        C:\> $Connection = 'Driver={Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb)};Dbq=C:\users\James\Documents\f1Results.xlsx;'
+        C:\> $dbPath = 'C:\users\James\Documents\f1Results.xlsx'

+        C:\> $SQL="SELECT top 25 DriverName, Count(RaceDate) as Races, Count(Win) as Wins, Count(Pole) as Poles, Count(FastestLap) as Fastlaps " +
+                   " FROM Results  GROUP BY DriverName ORDER BY (count(win)) DESC"
 
-        C:\> Send-SQLDataToExcel -Connection  $connection -SQL $sql -path .\demo1.xlsx -WorkSheetname "Winners" -AutoSize -AutoNameRange -ConditionalFormat @{DataBarColor="Blue"; Range="Wins"}
+        C:\> Send-SQLDataToExcel -Connection  $connection -SQL $sql -path .\demo2.xlsx -WorkSheetname "Winners" -AutoSize -AutoNameRange -ConditionalFormat @{DataBarColor="Blue"; Range="Wins"}
 
-        This declares a SQL statement and creates an  ODBC connection string to read from an Excel file, it then runs the statement and outputs the resulting data to a new spreadsheet.
+        Similar to the previous example this creates a connection string, this time for an Excel file, and runs
+        a SQL statement to get a list of motor-racing results, outputting the resulting data to a new spreadsheet.
         The spreadsheet is formatted and a data bar added to show make the drivers' wins clearer.

-        This uses Get-SQL (at least V1.1 - download from the gallery with Install-Module -Name GetSQL - note the function is Get-SQL the module is GetSQL without the "-" )
-        to simplify making database connections and building /submitting SQL statements.
-        Here it uses the same SQL statement as before; -OutputVariable leaves a System.Data.DataTable object in $table

-        Like the previous example, this uses Get-SQL (download from the gallery with Install-Module -Name GetSQL). It uses the connection which Get-SQL made rather than an ODFBC connection string
+        Like the previous example, this uses Get-SQL (download from the gallery with Install-Module -Name GetSQL).
+        It uses the database session which Get-SQL created, rather than an ODBC connection string.
+        The Session parameter can either be a object (as shown here), or the name used by Get-SQL ("F1" in this case).
         Here the data is presented as a quick chart.
