Writing a CSV File

Using PowerShell cmdlet Export-CSV

PowerShell objects can simply be piped to the Export-CSV cmdlet with a valid file name, which will convert the object into CSV format and write to the file. In the following example, we will first capture some services running on a Windows machine with specific properties and then export them to a file through the pipeline using the Export-CSV cmdlet. The use of the -NoTypeInformation switch parameter indicates that this cmdlet omits the type information from the CSV file, which is #TYPE followed by the fully qualified name of the type of object in the first line of the CSV file.

Get-Service win* | Select-Object Name, Status | Export-Csv C:\Temp\Service.csv -NoTypeInformation

We can even convert a dictionary to PowerShell objects by casting it to the [PSCustomObject] type accelerator. This will convert it into an object which we can then export to a CSV file using Export-CSV cmdlet.

Note: Run the cat Test.csv command after hitting the “Run” button to see the Test.csv file.
