I have JSON including multiple nested records. I want to add records with comma separated and store it in a CSV file.

Powershell Script

Actual Result

Expected Result

>Solution :

Use the -join operator to join 1 or more strings together with a given separator:

[PSCustomObject]@{
    # ...
    LicenseName = $LicenseName -join ', '
    LicenseURL = $LicenseURL -join ', '
}
