Proton has officially launched Proton Sheets, a new web-based spreadsheet platform designed to offer far stronger privacy than Google Sheets or Microsoft Excel. Every file and even its metadata are automatically encrypted, ensuring that no one—not even Proton—can access your information.
You can use Proton Sheets directly through your browser or via the Proton Drive app, making it simple and convenient to work securely from any device.
All the Spreadsheet Features You Love—with Next-Level Security
Even with its privacy-first approach, Proton Sheets still delivers a complete set of features you’d expect from a modern spreadsheet tool. Users can enjoy:
-
Real-time collaboration, similar to Google Sheets
-
CSV and XLS import, with instant encryption applied
-
Flexible access controls to share files only with trusted people
This means you get full functionality—just without the privacy risks.
Built to Protect Users from Big Tech’s Data and AI Risks
According to Anant Vijay Singh, Head of Proton Drive, Proton Sheets was created in response to growing concerns over how big tech companies use personal data, especially as AI models increasingly rely on user information for training.
With end-to-end encryption, Proton aims to give users a safer workspace where their data won’t be collected, analyzed, or exploited.
