B64-CSV-Decoder

A small script to decode Base64 cells in a CSV and output them as files.

Requirements

• Python3
• openpyxl library (pip3 install openpyxl)

Sample usage

python3 script.py -f test1.csv -o output -u -e txt

Notes

There is no definitive way to know if a string is Base64 encoded or just might be so it takes it's best guess. Some output files might be garbage.
