This example code shows how you can use VBScript to read and write standard text files. The code below can be used as a basis for reading lines from one file, processing them and then writing them back out to another file.

The example script can be used as a base for processing CSV, HTML and XML files.

To use the example paste the code into a text file and give it a .vbs extension.

Set oReadObj  = CreateObject("Scripting.FileSystemObject")
Set oWriteObj = CreateObject("Scripting.FileSystemObject")

Set oRead = oReadObj.OpenTextFile("input.txt", 1)
Set oWrite = oWriteObj.CreateTextFile("output.txt", True)

Dim strLine
Dim intLineCounter

intLineCounter = 0

Do Until oRead.AtEndOfStream

    strLine = oRead.ReadLine

    ' Process or modify the strLine variable here
    ' before it is written to the output file

    oWrite.WriteLine(strLine) 
    
    intLineCounter = intLineCounter + 1

Loop

oWrite.Close() ' Close output file
oRead.Close()  ' Close input file
