Abstract

The article introduces Proton Sheets, a new free, privacy-focused online spreadsheet application developed by Proton, designed as an alternative to Microsoft Excel and Google Sheets. Proton Sheets features end-to-end encryption (E2EE) to secure user data, integrates with Proton Drive for encrypted storage and file management, and supports importing and exporting Excel-compatible files, though it lacks support for some advanced Excel features and ODS files. It offers collaboration tools, conditional formatting, and version history, but is limited to online use with a 5GB storage cap on free accounts and fewer advanced functions compared to Excel. The service requires creating a Proton Drive account and emphasizes strong security practices, including safeguarding a unique recovery passphrase. [Extracted from the article]
