+
+        The first few lines of code export a list of file and directory names, sizes
+        and dates to a spreadsheet. It puts the date of the export in cell F1.
+        The first Conditional format changes the color of files and folders that begin
+        with a ".", "_" or anything else which sorts before "A".
+        The second Conditional format changes the Number format of numbers bigger than
+        1 million, for example 1,234,567,890 will dispay as "1,234.57M"
+        The third highlights datestamps of files less than a week old when the export
+        was run; the = is necessary in the condition value otherwise the rule will
+        look for the the text INT($F$1-7), and the cell address for the date is fixed
+        using the standard Excel $ notation.
+        The final Conditional format looks for files which have not changed since they
+        were created. Here the condition value is "=C2". The = sign means C2 is treated
+        as a formula, not literal text. Unlike the file age, we want the cell used to
+        change for each cell where the conditional format applies. The first cell in
+        the conditional format range is D2, which is compared against C2, then D3 is
+        compared against C3 and so on. A common mistake is to include the title row in
+        the range and accidentally apply conditional formatting to it, or to begin the
+        range at row 2 but use row 1 as the starting point for comparisons.
+      .Example
+        Add-ConditionalFormatting  $ws.Cells["B:B"] GreaterThan 10000000 -Fore  Red -Stop -Pri 1
+
+        This version shows the shortest syntax - the Address, Ruletype, and
+        Conditionvalue can be identified from their position, and ForegroundColor,
+        StopIfTrue and Priority can all be shortend.

+- Thank you to Conrad Agramont, Twitter: [@AGramont](https://twitter.com/@AGramont) for the `AddMultiWorkSheet.ps1` example. Much appreciated!
+- Fixed several more bugs where parameters were ignored if passed a zero value
+- Fixed bug where chart series headers could not come form a cell reference (=Sheet1!Z10 now works as a header reference)
+- Add-Chart will now allow a single X range, or as many X ranges as there are Y ranges.
+- Merge-MultipleSheets is more robust.
+- Set-ExcelRow and Set-ExcelColumn trap attempts to process a sheet with no rows/columns.
+- Help has been proof-read (thanks to Mrs. @Jhoneill !).

+- Thank you to (lazywinadmin)[https://github.com/lazywinadmin] - Expand aliases in examples and elsewhere
+- In Export-Excel fixed a bug where -AutoNameRange on pre-existing data included the header in the range.
+- In Export-Excel fixed a bug which caused a zero, null, or empty string in a list of simple objects to be skipped.
+- In Export-Excel improved the behaviour when a new worksheet is created without data, and Tables etc are added to it.
+- In Join-Worksheet: added argument completer to  -TitleBackgroundColor and set default for -TitleBackgroundStyle to 'Solid'.
+- In Add-Excel chart, New-ExcelChart, tests and Examples fixed mis-spelling of "Position"
+- In Send-SqlDataToExcel: improved robustness of check for no data returned.
+- In Set-ExcelColumn: -column can come from the pipeline (supporting an array introduces complications for supporting script blocks); -AutoNameRange no longer requires heading to specified (so you can do 1..10 | Set-ExcelColumn -AutoNameRange );  In Set-ExcelRow: -Row can come from the pipeline
+- Improved test coverage (back over 80%).
+- Help and example improvements. In "Index - music.ps1" the module for querying the index can be downloaded from PowerShell gallery #requires set to demand it. In SQL+FillColumns+Pivot\example2.ps1 the GetSQL module can be downloaded and #Requires has been set. The F1 results spreadsheet is available from one drive and a link is provided.

-        Compares two worksheets with the same name in different files.

+        rows in which they appear.
-        For the difference rows it adds the row number for the key of that row - we have to add the key after doing the comparison,
+        It then uses PowerShell's Compare-Object command to compare the sheets
-        otherwise rows will be considered as different simply because they have different row numbers
+        (explicitly checkingall the column names which have not been excluded).
-        We also add the name of the file in which the difference occurs.
+        For the difference rows it adds the row number for the key of that row -
-        If -BackgroundColor is specified the difference rows will be changed to that background.
+        we have to add the key after doing the comparison, otherwise identical
+        rows at different positions in the file will not be considered a match.
+        We also add the name of the file and sheet in which the difference occurs.
+        If -BackgroundColor is specified the difference rows will be changed to
+        that background in the orginal file.

-        Compare-WorkSheet -Referencefile 'Server56.xlsx' -Differencefile 'Server57.xlsx'  -WorkSheetName Products -key IdentifyingNumber -ExcludeProperty Install* | format-table

-        This builds on the previous example: this time Where two changed rows have the value in the "name" column (the default value for -key),

-        This time the reference file and the difference file are the same file and two different sheets are used. Because the tests include the
