How to merge colums of multiple text files into one csv file using PowerShell?

Question

I have got multiple measurement files with one column of numeric data each. (Update: The script should work for variable numbers of measurement files.)

Answer 1

You could try something like this:

$file1 = "C:\firstTxtFile.txt"
$file2 = "C:\SecondTxtFile.txt"
$outputFile = "C:\Output.txt"

$file1String = Get-content $file1 
$file2String = Get-content $file2

'"data1.dat","data2.dat"' > $outputFile

$counter = 0
while(($file1String[$counter] -ne $null) -and ($file2String[$counter] -ne $null)){
    $Line = $file1String[$counter] + "," + $file2String[$counter]
    $line >> $outputFile
    $counter++
}

This will take two text file and combine them into one output file.

Note: The output file will be overwritten each time this is run.
