Export-CSV exports length but not name

The previous answer does work, but what if someone was looking to output it into a CSV file.


This does NOT work:

$str_list = @('Mark','Henry','John')
$str_list | Export-Csv .\ExportStrList.csv -NoType

Because Export-Csv takes Objects and outputs properties. The only properties for a String[ ] is Length, so the CSV file only contains Lengths.

To fix this we need to change the String[ ] into an Object[ ]. The simplest way is with Select-Object.


Put each String into the Name property of a new Object[ ], like this:

$str_list = @('Mark','Henry','John')
$obj_list = $str_list | Select-Object @{Name='Name';Expression={$_}}
$obj_list | Export-Csv .\ExportStrList.csv -NoType

Just to re-iterate, Select-Object outputs a custom PSObject that can easily be manipulated. This is very powerful information, use it wisely.

Export-Csv exports a table of object properties and their values. Since your script is producing string objects, and the only property they have is length, that's what you got.

If you just want to save the list, use Out-File or Set-Content instead of Export-Csv.
