updated readme
New tests for compare worksheet, fixed a bug when the worksheets have different names and are not in the same file sometimes, you can't assume an order when they are diffed and the results grouped.
Moved "MoveTo…" functionality into Add-Worksheet and gave it copy worksheet functionality
Added create new file functionality to Open-ExcelPackage - requires a -create switch so previous "Open for read if it exists" behaviour is kept.
Fixed Conditional formatting so background pattern is "None" not "Solid" by default.
Tidied comments and help in Merge and Compare
Added Join Worksheet
Added Extra parameters, sanity check and help to New-PivotTableDefinition
Export-Excel.ps1
* Added MoveToStart, MoveBefore and MoveAfter Parameters
* Added support for URI item properties. If a property is of type URI it is created as a hyperlink
* Fixed issue where AutoNamedRange, NamedRange, and TableName do not work when appending to a sheet which already contains the range(s) / table
* Fixed issues when pivottables / charts already exist and an export tries to create them again.
* Allowed PivotFilter and PivotDataToColumn, ChartHeight/width ChartRow/Column, ChartRow/ColumnPixelOffsets, to be passed in -PivotTableDefinition and specified when running New-PivotDefinition.
* Bad column-names specified for Pivots now generate warnings instead of throwing.
* Removed the need to specify a fill type when specifying a title background color
* "flattened out" small "called-once" function , add-title, convert-toNumber and Stop-ExcelProcess.
Start row already existed.
Aliases allow you to specify -no header -top 10 -bottom 20 -left 6 -right 8
Start row can be below end right row, and start (left) column can be to the right of the end column - this allows read in reverse order, but does generate a warning.
