powershell - Remove New Line Character from CSV file's string column

I have a CSV File with a string column were that column spans to multiple lines. I want to aggregate those multiple lines into one line.

For example

1, "asdsdsdsds", "John"
2, "dfdhifdkinf
dfjdfgkdnjgknkdjgndkng
dkfdkjfnjdnf", "Roy"
3, "dfjfdkgjfgn", "Rahul"

I want my output to be

1, "asdsdsdsds", "John"
2, "dfdhifdkinf dfjdfgkdnjgknkdjgndkng dkfdkjfnjdnf", "Roy"
3, "dfjfdkgjfgn", "Rahul"

I want to achieve this output using PowerShell

Thanks.

Building on Ansgar's answer, here's how to do it when:

  • You don't know the column names
  • Your CSV file may contain CR or LF independently

    (Import-Csv $csvInput) | % {
        $line = $_
        foreach ($prop in $line.PSObject.Properties) {
            $line.($prop.Name) = ($prop.Value -replace '[
    ]',' ')
        }
        $line
    } | Export-Csv $csvOutput -NoTypeInformation
