Discover Workbook Password

Hello,

I have an old file in my archive folder, and I happened to lost the password. I remember it had something to do with a year, but I cannot remember anything...
I already searched only for tools, and all that I found was paid...I also tried the "ZIP" trick but it seems that it doesn't work anymore (I get an error when trying to open the ZIP).

Do you know any other way to unlock/discover the password? I can try anything! Even to create some code in Python maybe to try to bruteforce it...

Thanks in advance!
