On the contrary, I encourage you to see how far you can go!
I completed the first six days* of last year’s challenges using only Google Sheets (and a bit of text formatting with Notepad++).
I learned a lot about some of the more advanced techniques and functions, and I had a lot of fun doing it!
In a way, spreadsheets might embody the most popular functional language and REPL in the world.
(*) IIRC, I stopped at Day 7 because it involved recursion (walking a tree, I think). After a bit of investigation, I concluded that it might still be possible to use a spreadsheet but the situation would result in me fighting the tool.
