Proton Sheets provides encrypted online spreadsheets for organizing data and collaborating, with Excel and Google Sheets import.
About Proton Sheets
Proton Sheets is an online spreadsheet application from Proton for organizing, analyzing, and sharing data. Files are kept in an end-to-end encrypted workspace. Users can import existing Excel and Google Sheets files, build charts and tables, use built-in formulas, and edit the same worksheet with other people in real time. It is part of Proton Drive, Proton's encrypted cloud storage service.
According to Proton, the workspace is protected by Swiss privacy laws, and only the owner and people the owner chooses can access a sheet. These are vendor statements from the homepage, not independently verified guarantees. Because Sheets is an online service within Proton Drive, data is stored in the cloud. The homepage describes a free account and a business offering but does not state prices, plan details, or any geographic or usage limits.
