Export-Excel, format column as text?

[mtengmo]

Is it possible to format columns so it´s text? because I´m losing leading zero´s if it´s zipcodes that starts with 0.
I´m using this code:
$HRCemployees | Export-excel "$file.xlsx" -NoNumberConversion:$true

$HRCemployees | Export-excel "$file.xlsx" -NoNumberConversion *
Solved it.
