Some years ago I started using VBA (Visual Basic for Applications, included in many office suites for windows) to to automatic tasks where I previously used qbasic or command-line scripts. Here you'll see some of them:

• Unzip using shell32.dll and cscript Unzip from command line using cscript.
• base64decode (in Spanish) Decode base64 strings. Useful to decrypt email sources or base64 POST strings.
