PowerShell Import-Excel

This PowerShell Module allows you to read and write Excel files without installing Microsoft Excel on your system. No need to bother with the cumbersome Excel COM-objects thanks to the .NET EPPlus DLL (http://epplus.codeplex.com/) which is included in the module. Creating Tables, Pivot Tables, Charts and much more has just become a lot easier.

Installation

PowerShell V5 and Later

You can install the ImportExcel module directly from the PowerShell Gallery

  • [Recommended] Install to your personal PowerShell Modules folder
Install-Module ImportExcel -scope CurrentUser
  • [Requires Elevation] Install for Everyone (computer PowerShell Modules folder)
Install-Module ImportExcel

PowerShell V4 and Earlier

To install to your personal modules folder (e.g. ~\Documents\WindowsPowerShell\Modules), run:

iex (new-object System.Net.WebClient).DownloadString('https://raw.github.com/dfinke/ImportExcel/master/Install.ps1')

What's new

10/30/2017

Huge thanks to James O'Neill. PowerShell aficionado. He always brings a flare when working with PowerShell. This is no exception.

(Check out the examples help Export-Excel -Examples)

  • New parameter Package allows an ExcelPackage object returned by -passThru to be passed in

  • New parameter ExcludeProperty to remove unwanted properties without needing to go through select-object

  • New parameter Append code to read the existing headers and move the insertion point below the current data

  • New parameter ClearSheet which removes the worksheet and any past data

  • Remove any existing Pivot table before trying to [re]create it

  • Check for inserting a pivot table so if -InsertPivotChart is specified it implies -InsertPivotTable

(Check out the examples help Export-Excel -Examples)

  • New function Export-Charts (requires Excel to be installed) - Export Excel charts out as JPG files
  • New function Add-ConditionalFormatting Adds contitional formatting to worksheet
  • New function Set-Format Applies Number, font, alignment and colour formatting to a range of Excel Cells
  • ColorCompletion an argument completer for Colors for params across functions

I also worked out the parameters so you can do this, which is the same as passing -Now. It creates an Excel file name for you, does an auto fit and sets up filters.

ps | select Company, Handles | Export-Excel

Added New-PivotTableDefinition. You can create and wire up a PivotTable to a WorkSheet. You can also create as many PivotTable Worksheets to point a one Worksheet. Or, you create many Worksheets and many corresponding PivotTable Worksheets.

Here you can create a WorkSheet with the data from Get-Service. Then create four PivotTables, pointing to the data each pivoting on a differnt dimension and showing a differnet chart

$base = @{
    SourceWorkSheet   = 'gsv'
    PivotData         = @{'Status' = 'count'}
    IncludePivotChart = $true
}

$ptd = [ordered]@{}

$ptd += New-PivotTableDefinition @base servicetype -PivotRows servicetype -ChartType Area3D
$ptd += New-PivotTableDefinition @base status -PivotRows status -ChartType PieExploded3D
$ptd += New-PivotTableDefinition @base starttype -PivotRows starttype -ChartType BarClustered3D
$ptd += New-PivotTableDefinition @base canstop -PivotRows canstop -ChartType ConeColStacked

Get-Service | Export-Excel -path $file -WorkSheetname gsv -Show -PivotTableDefinition $ptd

10/4/2017

Thanks to https://github.com/ili101 :

  • Fix Bug, Unable to find type [PSPlot]
  • Fix Bug, AutoFilter with TableName create corrupted Excel file.

10/2/2017

Thanks to Jeremy Brun Fixed issues related to use of -Title parameter combined with column formatting parameters.

9/28/2017 (Version 4.0.1)

  • Added a new parameter called Password to import password protected files
  • Added even more Pester tests for a more robust and bug free module
  • Renamed parameter 'TopRow' to 'StartRow' This allows us to be more concise when new parameters ('StartColumn', ..) will be added in the future Your code will not break after the update, because we added an alias for backward compatibility

Special thanks to robinmalik for providing us with the code to implement this new feature. A high five to DarkLite1 for the implementation.

9/12/2017 (Version 4.0.0)

Super thanks and hat tip to DarkLite1. There is now a new and improved Import-Excel, not only in functionality, but also improved readability, examples and more. Not only that, he's been running it in production in his company for a number of weeks!

Added Update-FirstObjectProperties Updates the first object to contain all the properties of the object with the most properties in the array. Check out the help.

Breaking Changes: Due to a big portion of the code that is rewritten some slightly different behavior can be expected from the Import-Excel function. This is especially true for importing empty Excel files with or without using the TopRow parameter. To make sure that your code is still valid, please check the examples in the help or the accompanying Pester test file.

Moving forward, we are planning to include automatic testing with the help of Pester, Appveyor and Travis. From now on any changes in the module will have to be accompanied by the corresponding Pester tests to avoid breakages of code and functionality. This is in preparation for new features coming down the road.

7/3/2017

Thanks to Mikkel Nordberg. He contributed a ConvertTo-ExcelXlsx. To use it, Excel needs to be installed. The function converts the older Excel file format ending in .xls to the new format ending in .xlsx.

6/15/2017

Huge thank you to DarkLite1! Refactoring of code, adding help, adding features, fixing bugs. Specifically this long outstanding one:

Export-Excel: Numeric values not correct

It is fantastic to work with people like DarkLite1 in the community, to help make the module so much better. A hat to you.

Another shout out to Damian Reeves! His questions turn into great features. He asked if it was possible to import an Excel worksheet and transform the data into SQL INSERT statements. We can now answer that question with a big YES!

ConvertFrom-ExcelToSQLInsert People .\testSQLGen.xlsx
INSERT INTO People ('First', 'Last', 'The Zip') Values('John', 'Doe', '12345');
INSERT INTO People ('First', 'Last', 'The Zip') Values('Jim', 'Doe', '12345');
INSERT INTO People ('First', 'Last', 'The Zip') Values('Tom', 'Doe', '12345');
INSERT INTO People ('First', 'Last', 'The Zip') Values('Harry', 'Doe', '12345');
INSERT INTO People ('First', 'Last', 'The Zip') Values('Jane', 'Doe', '12345');

Bonus Points

Use the underlying ConvertFrom-ExcelData function and you can use a scriptblock to format the data however you want.

ConvertFrom-ExcelData .\testSQLGen.xlsx {
    param($propertyNames, $record)

    $reportRecord = @()
    foreach ($pn in $propertyNames) {
        $reportRecord += "{0}: {1}" -f $pn, $record.$pn
    }
    $reportRecord +=""
    $reportRecord -join "`r`n"
}

Generates

First: John
Last: Doe
The Zip: 12345

First: Jim
Last: Doe
The Zip: 12345

First: Tom
Last: Doe
The Zip: 12345

First: Harry
Last: Doe
The Zip: 12345

First: Jane
Last: Doe
The Zip: 12345

2/2/2017

Thank you to DarkLite1 for more updates

  • TableName with parameter validation, throws an error when the TableName:
    • Starts with something else then a letter
    • Is NULL or empty
    • Contains spaces
  • Numeric parsing now uses CurrentInfo to use the system settings

2/14/2017

Big thanks to DarkLite1 for some great updates

  • -DataOnly switch added to Import-Excel. When used it will only generate objects for rows that contain text values, not for empty rows or columns.

  • Get-ExcelWorkBookInfo - retrieves information of an Excel workbook.

  • Added -Now switch. This short cuts the process, automatically creating a temp file and enables the -Show, -AutoFilter, -AutoSize switches.
Get-Process | Select Company, Handles | Export-Excel -Now
  • Added ScriptBlocks for coloring cells. Check out Examples
Get-Process |
    Select-Object Company,Handles,PM, NPM|
    Export-Excel $xlfile -Show  -AutoSize -CellStyleSB {
        param(
            $workSheet,
            $totalRows,
            $lastColumn
        )

        Set-CellStyle $workSheet 1 $LastColumn Solid Cyan

        foreach($row in (2..$totalRows | Where-Object {$_ % 2 -eq 0})) {
            Set-CellStyle $workSheet $row $LastColumn Solid Gray
        }

        foreach($row in (2..$totalRows | Where-Object {$_ % 2 -eq 1})) {
            Set-CellStyle $workSheet $row $LastColumn Solid LightGray
        }
    }

9/28/2016

Fixed PowerShell 3.0 compatibility. Thanks to headsphere. He used $obj.PSObject.Methods[$target] snytax to make it backward compatible. PS v4.0 and later allow $obj.$target.

Thank you to xelsirko for fixing - Import-module importexcel gives version warning if started inside background job

8/12/2016

Fixed reading the headers from cells, moved from using Text property to Value property.

7/30/2016

    where company |
    select Company,PagedMemorySize,PeakPagedMemorySize |
    Export-Excel $file -Show -AutoSize `
        -IncludePivotTable `
        -IncludePivotChart `
        -ChartType ColumnClustered `
        -PivotRows Company `
        -PivotData @{PagedMemorySize='sum';PeakPagedMemorySize='sum'}

Add -PivotDataToColumn

$file = "C:\Temp\ps.xlsx"
rm $file -ErrorAction Ignore

ps |
    where company |
    select Company,PagedMemorySize,PeakPagedMemorySize |

    Plot($t,$t, $t,$t2, $t,$t3).
    SetChartPosition("i").
    SetChartSize(500,500).
    Title("Hello World").
    Show()

3/31/2016

  • Thanks to redoz Multi Series Charts are now working

Also check out how you can create a table and then with Excel notation, index into the data for charting "Impressions[A]"

$data = @"
A,B,C,Date
2,1,1,2016-03-29
5,10,1,2016-03-29
"@ | ConvertFrom-Csv

$c = New-ExcelChart -Title Impressions `
    -ChartType Line -Header "Something" `

10/20/2015

Big bug fix for version 3.0 PowerShell folks!

This technique fails in 3.0 and works in 4.0 and later.

$m="substring"
"hello".$m(2,1)

Adding .invoke works in 3.0 and later.

$m="substring"
"hello".$m.invoke(2,1)

A big thank you to DarkLite1 for adding the help to Export-Excel.

Added -HeaderRow parameter. Sometimes the heading does not start in Row 1.

10/16/2015

Fixes Export-Excel generates corrupt Excel file

10/15/2015

Import-Excel has a new parameter NoHeader. If data in the sheet does not have headers and you don't want to supply your own, Import-Excel will generate the property name.

Import-Excel now returns .Value rather than .Text

10/1/2015

Merged ValidateSet for Encoding and Extension. Thank you Irwin Strachan.

9/30/2015

Export-Excel can now handle data that is not an object

echo a b c 1 $true 2.1 1/1/2015 | Export-Excel c:\temp\test.xlsx -Show

Or

dir -Name | Export-Excel c:\temp\test.xlsx -Show

9/25/2015

Hide worksheets Got a great request from forensicsguy20012004 to hide worksheets. You create a few pivotables, generate charts and then pivotable worksheets don't need to be visible.

Export-Excel now has a -HideSheet parameter that takes and array of worksheet names and hides them.

Example

Here, you create four worksheets named PM,Handles,Services and Files.

The last line creates the Files sheet and then hides the Handles,Services sheets.

$p = Get-Process

$p|select company, pm | Export-Excel $xlFile -WorkSheetname PM
$p|select company, handles| Export-Excel $xlFile -WorkSheetname Handles
Get-Service| Export-Excel $xlFile -WorkSheetname Services

dir -File | Export-Excel $xlFile -WorkSheetname Files -Show -HideSheet Handles, Services

Note There is a bug in EPPlus that does not let you hide the first worksheet created. Hopefully it'll resolved soon.

9/11/2015

Added Conditional formatting. See TryConditional.ps1 as an example.

Or, check out the short "How To" video.

  • For -PivotRows you can pass a hashtable with the name of the property and the type of calculation. Sum, Average, Max, Min, Product, StdDev, StdDevp, Var, Varp
Get-Service |
	Export-Excel "c:\temp\test.xlsx" `
		-Show `
		-IncludePivotTable `
		-PivotRows status `
		-PivotData @{status='count'}

6/16/2015 (Thanks Justin)

  • Improvements to PivotTable overwriting
  • Added two parameters to Export-Excel
    • RangeName - Turns the data piped to Export-Excel into a named range.
    • TableName - Turns the data piped to Export-Excel into an excel table.

Examples

Get-Process|Export-Excel foo.xlsx -Verbose -IncludePivotTable -TableName "Processes" -Show
Get-Process|Export-Excel foo.xlsx -Verbose -IncludePivotTable -RangeName "Processes" -Show

5/25/2015

  • Fixed null header problem

5/17/2015

  • Added three parameters:
    • FreezeTopRow - Freezes the first row of the data
    • AutoFilter - Enables filtering for the data in the sheet
    • BoldTopRow - Bolds the top row of data, the column headers

Example

Get-CimInstance win32_service |
	select state, accept*, start*, caption |
	Export-Excel test.xlsx -Show -BoldTopRow -AutoFilter -FreezeTopRow -AutoSize

image

5/4/2015

  • Published to PowerShell Gallery. In PowerShell v5 use Find-Module importexcel then Find-Module importexcel | Install-Module

4/27/2015

  • datetime properties were displaying as ints, now are formatted

4/25/2015

  • Now you can create multiple Pivot tables in one pass
    • Thanks to pscookiemonster, he submitted a repro case to the EPPlus CodePlex project and got it fixed

Example

$ps = ps

$ps |
    Export-Excel .\testExport.xlsx  -WorkSheetname memory `
        -IncludePivotTable -PivotRows Company -PivotData PM `
        -IncludePivotChart -ChartType PieExploded3D
$ps |
    Export-Excel .\testExport.xlsx  -WorkSheetname handles `
        -IncludePivotTable -PivotRows Company -PivotData Handles `
        -IncludePivotChart -ChartType PieExploded3D -Show

4/20/2015

  • Included and embellished Claus Nielsen function to take all sheets in an Excel file workbook and create a text file for each ConvertFrom-ExcelSheet
  • Renamed Export-MultipleExcelSheets to ConvertFrom-ExcelSheet

4/13/2015

  • You can add a title to the Excel "Report" Title, TitleFillPattern, TitleBold, TitleSize, TitleBackgroundColor
    • Thanks to Irwin Strachan for this and other great suggestions, testing and more

4/10/2015

  • Renamed AutoFitColumns to AutoSize
  • Implemented Export-MultipleExcelSheets
  • Implemented -Password for a worksheet
  • Replaced -Force switch with -NoClobber switch
  • Added examples for Get-Help
  • If Pivot table is requested, that sheet becomes the tab selected

4/8/2015

  • Implemented exporting data to named sheets via the -WorkSheetname parameter.

Examples

gsv | Export-Excel .\test.xlsx -WorkSheetname Services

dir -file | Export-Excel .\test.xlsx -WorkSheetname Files

ps | Export-Excel .\test.xlsx -WorkSheetname Processes -IncludePivotTable -Show -PivotRows Company -PivotData PM

Convert (All or Some) Excel Sheets to Text files

Reads each sheet in TestSheets.xlsx and outputs it to the data directory as the sheet name with the extension .txt

ConvertFrom-ExcelSheet .\TestSheets.xlsx .\data

Reads and outputs sheets like Sheet10 and Sheet20 form TestSheets.xlsx and outputs it to the data directory as the sheet name with the extension .txt

ConvertFrom-ExcelSheet .\TestSheets.xlsx .\data sheet?0

Example Adding a Title

You can set the pattern, size and of if the title is bold.

$p=@{
    Title = "Process Report as of $(Get-Date)"
    TitleFillPattern = "LightTrellis"
    TitleSize = 18
    TitleBold = $true

	Path  = "$pwd\testExport.xlsx"
    Show = $true
    AutoSize = $true
}

Get-Process |
    Where Company | Select Company, PM |
    Export-Excel @p

image

Example Export-MultipleExcelSheets

image

$p = Get-Process

$DataToGather = @{
    PM        = {$p|select company, pm}
    Handles   = {$p|select company, handles}
    Services  = {gsv}
    Files     = {dir -File}
    Albums    = {(Invoke-RestMethod http://www.dougfinke.com/PowerShellfordevelopers/albums.js)}
}

Export-MultipleExcelSheets -Show -AutoSize .\testExport.xlsx $DataToGather

NOTE If the sheet exists when using -WorkSheetname parameter, it will be deleted and then added with the new data.

Known Issues

  • Using -IncludePivotTable, if that pivot table name exists, you'll get an error.
    • Investigating a solution
    • Workaround delete the Excel file first, then do the export
