ASCII and UTF-8 are two of the ways in which computers store letters and symbols using binary.
ASCII stands for the American Standard Code for Information Interchange. It’s a system used to represent English characters, and it was designed to encode 128 different characters.

After you have decoded it how could the spreadsheet be modified to encode messages?

If you know a bit of Python this tutorial is a good extension for you.
You will get to run some Python code that can convert characters to numbers and back again.
Want a real challenge? In the end I challenge you to use this knowledge to encrypt/decrypt a message using a Caesar Cipher.
