Powershell – Remove Columns From Fixed Width Files

Here is something that works incredibly well.

This is a quick description enter the file names you wish to use. Powershell then reads in all the data and creates a new file by joining all the elements in the char array to a string. It then takes the row and ends it in a carriage return / line feed. Finally it saves the file.

$fileName = c:\file.txt
$newFileName = c:\newfile.txt
$newFile = “”
Get-Content -Path $filename | ForEach-Object{$newFile += [string]::Join(“”,$_[0..149] + $_[154..777]) + “`r`n”}
$newfile > $newFileName
