Function Export-XLSX { <# .SYNOPSIS Export data to an XLSX file .DESCRIPTION Export data to an XLSX file .PARAMETER InputObject Data to export .PARAMETER Path Path to the file to export .PARAMETER WorksheetName Name the worksheet you are importing to .PARAMETER Header Header to use. Must match order and count of your data's properties .PARAMETER AutoFit If specified, autofit everything .PARAMETER PivotRows If specified, add pivot table pivoting on these rows .PARAMETER PivotColumns If specified, add pivot table pivoting on these columns .PARAMETER PivotValues If specified, add pivot table pivoting on these values .PARAMETER PivotFunction If specified, use this summary mode for pivot values (defaults to Count mode) .PARAMETER ChartType If specified, add pivot chart of this type .PARAMETER Table If specified, add table to all cells .PARAMETER TableStyle If specified, add table style .PARAMETER Append If specified, append to existing worksheet. We don't check header names, but header count must match. .PARAMETER Force If file exists, overwrite it. .PARAMETER ClearSheet If worksheet with the same name exists, clear it before filling it in .PARAMETER RemoveSheet If worksheet with the same name exists, remove it and re-add it .PARAMETER Passthru If specified, we re-open the ExcelPackage and return it .EXAMPLE $Files = Get-ChildItem C:\ -File Export-XLSX -Path C:\Files.xlsx -InputObject $Files Export file listing to C:\Files.xlsx .EXAMPLE $Files = Get-ChildItem C:\ -File $Worksheet = 'Files' Export-XLSX -Path C:\temp\Files.xlsx -InputObject $Files -WorksheetName $Worksheet -ClearSheet Export file listing to C:\temp\Files.xlsx to the worksheet named "Files". If it exists already, clear the sheet then import the data. .EXAMPLE 1..10 | Foreach-Object { New-Object -typename PSObject -Property @{ Something = "Prop$_" Value = Get-Random } } | Select-Object Something, Value | Export-XLSX -Path C:\Random.xlsx -Force -Header Name, Val # Generate data # Send it to Export-XLSX # Give it new headers # Overwrite C:\random.xlsx if it exists .EXAMPLE # Create XLSX Get-ChildItem -file | Export-XLSX -Path C:\temp\multi.xlsx # Add a second worksheet to the xlsx Get-ChildItem -file | Export-XLSX -Path C:\temp\multi.xlsx -WorksheetName "Two" .EXAMPLE # Create XLSX Get-ChildItem -file | Export-XLSX -Path C:\temp\multi.xlsx # Add a second worksheet to the xlsx Get-ChildItem -file | Export-XLSX -Path C:\temp\multi.xlsx -WorksheetName "Two" # I don't like that second worksheet. Recreate it, deleting the existing worksheet if it exists. Get-ChildItem -file | Select -first 1 | Export-XLSX -Path C:\temp\multi.xlsx -WorksheetName "Two" -ReplaceSheet .EXAMPLE Get-ChildItem C:\ -file | Export-XLSX -Path C:\temp\files.xlsx -PivotRows Extension -PivotValues Length -ChartType Pie # Get files # Create an xlsx in C:\temp\files.xlsx # Pivot rows on 'Extension' # Pivot values on 'Length # Add a pie chart # This example gives you a pie chart breaking down storage by file extension .EXAMPLE Get-Process | Export-XLSX -Path C:\temp\process.xlsx -Worksheet process -Table -TableStyle Medium1 -AutoFit # Get all processes # Create an xlsx # Create a table with the Medium1 style and all cells autofit on the 'process' worksheet .EXAMPLE # # This example illustrates appending data 1..10 | Foreach-Object { New-Object -typename PSObject -Property @{ Something = "Prop$_" Value = Get-Random } } | Select-Object Something, Value | Export-XLSX -Path C:\Random.xlsx -Force # Generate data # Send it to Export-XLSX # Overwrite C:\random.xlsx if it exists 1..5 | Foreach-Object { New-Object -typename PSObject -Property @{ Something = "Prop$_" Value = Get-Random } } | Select-Object Something, Value | Export-XLSX -Path C:\Random.xlsx -Append # Generate data # Send it to Export-XLSX # Append to C:\random.xlsx .NOTES Thanks to Doug Finke for his example The pivot stuff is straight from Doug: https://github.com/dfinke/ImportExcel Thanks to Philip Thompson for an expansive set of examples on working with EPPlus in PowerShell: https://excelpslib.codeplex.com/ .LINK https://github.com/RamblingCookieMonster/PSExcel .FUNCTIONALITY Excel #> [CmdletBinding(DefaultParameterSetName='Path')] param( [parameter( ParameterSetName='Path', Position = 0, Mandatory=$true )] [ValidateScript({ $Parent = Split-Path $_ -Parent if( -not (Test-Path -Path $Parent -PathType Container) ) { Throw "Specify a valid path.
