How does export-csv cmdlet create a csv file?


Asked by Santino Lynn on Dec 01, 2021 FAQ



The Export-CSV cmdlet creates a CSV file of the objects that you submit. Each object is represented as a line or row of the CSV. The row consists of a comma-separated list of the values of object properties.
Accordingly,
Converts objects into a series of comma-separated (CSV) strings and saves the strings in a CSV file. The Export-CSV cmdlet creates a CSV file of the objects that you submit. Each object is represented as a line or row of the CSV.
Also, You can pipe any object to Export-CSV cmdlet in PowerShell to write to CSV file. Output of Export-CSV cmdlet is CSV string saved to file on location specified by Path parameter. You can find more topics about PowerShell Active Directory commands and PowerShell basics on ShellGeek home page.
Keeping this in consideration,
If Export-CSV receives formatted objects the CSV file contains the format properties rather than the object properties. To export only selected properties of an object, use the Select-Object cmdlet. This example selects Process objects with specific properties, exports the objects to a CSV file. The Get-Process cmdlet gets the Process objects.
Thereof,
By default, the Import-Csv cmdlet will treat the top row of the CSV file as headers. It will then convert these values in properties of each row (object). But if you have a CSV file that does not have a header row, you can use the Header parameter to define one yourself.
