Append/prepend data to CSV column

I have spent over a week researching this question and none of the helps have worked. I started with this:



$File = "C:FOLDERindex - Copy.csv"
Import-Csv -Delim ',' $File |
ForEach-Object $_.col1 = "C:FOLDER$($_.col1)"; $_ |
Export-Csv Index2.csv -Delim ',' -NoTypeInformation


which I found elsewhere on this site and modified as I would expect. But I received this error:




Exception setting "col1": "The property 'col1' cannot be found on this object.
Verify that the property exists and can be set."
At line:2 char:69
+ Import-Csv -Delim ',' $File | ForEach-Object {$_.col1 = "C:FOLDER$($_.col1)";$_ ...
+ ~~~~~~~
+ CategoryInfo : NotSpecified: (:) [], SetValueInvocationException
+ FullyQualifiedErrorId : ExceptionWhenSetting


All I want to do is take a CSV file that looks like this:




Path,Filename
123456789,654321
234567891,543216
345678912,432165


and ultimately end with this:




Path,Filename
C:FOLDER123456789.jpg,654321.jpg
C:FOLDER234567891.jpg,543216.jpg

  • What is not clear about the error? Your CSV does not have a column named "col1". Use the actual column name(s) instead.
