Pipe CSV Data to CSV in PowerShell

Use standard PowerShell cmdlets to access CSV tables.

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

Creating a Connection to Your CSV Data

The DataSource property must be set to a valid local folder name. Also, specify the IncludeFiles property to work with text files having extensions that differ from .csv, .tab, or .txt. Specify multiple file extensions in a comma-separated list. You can also set Extended Properties compatible with the Microsoft Jet OLE DB 4.0 driver. Alternatively, you can provide the format of text files in a Schema.ini file.

$conn = Connect-CSV  -DataSource "$DataSource"

Selecting Data

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

Select-CSV -Connection $conn -Table Customer | Select -Property * -ExcludeProperty Connection,Table,Columns | Export-Csv -Path c:\myCustomerData.csv -NoTypeInformation

You will notice that we piped the results from Select-CSV 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.

The Connection, Table, and Columns are appended to the results in order to facilitate piping results from one of the CData Cmdlets directly into another one.
