I have this csv file I'm trying to remove leading zeros from, but with my code for any numbers that have letters or special characters, it nulls out the value, and I don't want that...

Now I use the following code to remove the leading zeros...
Write-Host "Removing leading zeros from column `"column1`" in C:\path\test.csv"
Import-Csv "C:\path\test.csv" |
select -Property @{n='column1';e={[int]$_.column1}},* -Exclude 'column1' |
Export-Csv "C:\path\testtemp" -NoTypeInformation
Move-Item "C:\path\testtemp" "C:\path\test.csv" -Force
Write-Host "Complete"
The issue is where the strings (with alpha and special characters) could not be converted into [int], they get removed as shown below...
"column1" ,"column2" ,"column3" ,"column4" ,"column5","column6","column7","column8" ,"column9","column10","column11","column12","column13","column14","column15","column16"

What I Have Tried So Far...
I have tried editing the code to the following...
Write-Host "Removing leading zeros from column `"column1`" in C:\path\test.csv"
Import-Csv "C:\path\test.csv" |
select -Property @{n='column1';e={If(([int]$_.column1 -ne $null) -or ([int]$_.column1 -ne "")){[int]$_.column1}Else{$_.column1}}},* -Exclude 'column1' |
Export-Csv "C:\path\testtemp" -NoTypeInformation
Move-Item "C:\path\testtemp" "C:\path\test.csv" -Force
Write-Host "Complete"
But the result of not adding the non-int values is still the same. If anyone could help me with the syntax I would be grateful.
Try using ".TrimStart()" to take out the zeros.
Import-CSV "C:\path\test.csv" | ForEach-Object{
$_.column1 = ($_.column1).TrimStart('0')
$_
} | Export-Csv "C:\path\test2.csv" -NoTypeInformation
Move-Item "C:\path\test2.csv" "C:\path\test.csv" -Force
Note that in order for this to work, I had to reformat your first column to take out the extra spaces. Thus, the header in the original csv would start with: column1,column2, and so on.
