Proton End-to-end Encrypted Spreadsheets

I must admit that Proton recently released a feature-rich spreadsheet program that is truly end-to-end encrypted, something I was unaware I had been waiting for. Like Docs, it resides inside Proton Drive and is known as Proton Sheets.

It has the same feel as Google Sheets or Excel, but no one can see your data, not even Proton. Pivot tables, formulas, importing CSVs, and sharing with particular individuals (or password-protected links for outsiders) are all helpful and not merely a privacy ploy.

Having a genuine alternative that doesn't force me to choose between functionality and privacy feels almost too good to be true, as someone who has previously been let down by "convenient" tools that silently gather everything.
