Pipe Excel Data to CSV in PowerShell

The CData Cmdlets Module for Excel is a standard PowerShell module offering straightforward integration with Excel. Below, you will find examples of using our Excel Cmdlets with native PowerShell cmdlets.

Creating a Connection to Your Excel Data

The ExcelFile, under the Authentication section, must be set to a valid Excel File.

$conn = Connect-Excel  -Excel File "$Excel File"

Selecting Data

Follow the steps below to retrieve data from the Sheet table and pipe the result into to a CSV file:

Select-Excel -Connection $conn -Table Sheet | Select -Property * -ExcludeProperty Connection,Table,Columns | Export-Csv -Path c:\mySheetData.csv -NoTypeInformation

You will notice that we piped the results from Select-Excel into a Select-Object cmdlet and excluded some properties before piping them into an Export-Csv cmdlet. We do this because the CData Cmdlets append Connection, Table, and Columns information onto each "row" in the result set, and we do not necessarily want that information in our CSV file.

Deleting Data

The following line deletes any records that match the criteria:

Select-Excel -Connection $conn -Table Sheet -Where "Name = Bob" | Remove-Excel

Inserting and Updating Data

The cmdlets make data transformation easy as well as data cleansing. The following example loads data from a CSV file into Excel, checking first whether a record already exists and needs to be updated instead of inserted.

Import-Csv -Path C:\MySheetUpdates.csv | %{
  $record = Select-Excel -Connection $Excel -Table Sheet -Where ("Id = `'"+$_.Id+"`'")
  if($record){
    Update-Excel -Connection $excel -Table Sheet -Columns ("Name","Revenue") -Values ($_.Name, $_.Revenue) -Where ("Id = `'"+$_.Id+"`'")
  }else{
    Add-Excel -Connection $excel -Table Sheet -Columns ("Name","Revenue") -Values ($_.Name, $_.Revenue)
  }
}

As always, our goal is to simplify the way you connect to data. With cmdlets users can install a data module, set the connection properties, and start building. Download Cmdlets and start working with your data in PowerShell today!
