Leading zero is dropped when using ExportTo-Csv cmdlet - csv

Question

Below is the script I am running.
The script is working fine. It is giving proper output, however it is removing leading zeros from couple of columns. Please suggest how to retain leading zero for the integer fields.
I am using
$res.data.Tables[0] | ConvertTo-Csv -NoType | ForEach-Object {$_.Replace('"','')} | Out-file $fileName -Force"
for exporting data to the CSV file. Please suggest how to retain the leading zeros (at least 2 decimal places).

Integers don't have "leading zeroes". If you want to export formatted output you need to convert the respective fields to formatted strings, e.g. like this:
$res.data.Tables[0] |
Select-Object FieldA, FieldB, #{n='FieldC';e={'{0:d2}' -f $_.FieldC}},
#{n='FieldD';e={'{0:d2}' -f $_.FieldD}}, FieldE, ... |
ConvertTo-Csv -NoType |
...
