Need a password for an encrypted XLSX excel spreadsheet - Deeglifsay - Nov 29, 2018
What're my options? It prompts for a password when I attempt to open the file. It's the newer version of Excel, so the 2010/2013 exploits and tricks didn't work.

Hmm what .. exploits against 128 AES? Key recovery attacks will only take a 1/4 billion years much better than the 1 billion years right .. still your great great great (x8) grand child will be dust.
Your option is going to be prayer and bruteforce https://hackforums.net/showthread.php?tid=5912770
