It's funny you say this because I tried using Excel for basic fitness/nutrition tracking and it wouldn't let me because my Windows 10 license was having issues with Office.

I opened up Google Sheets and haven't looked back. I can update any spreadsheet from my phone and it's backed up on my Google Drives account. Would have given Microsoft a chance had they not been so particular about who can use their software.

I've used Excel for over a decade and am baffled by how restrictive the licensing has become.
