# Proton Sheets

> End-to-end encrypted online spreadsheets inside Proton Drive

Proton Sheets is the spreadsheet editor built into Proton Drive. Spreadsheets are end-to-end encrypted by default, so only the owner and the people a file is shared with can read them, and collaborators can edit the same sheet in real time. It is free with any Proton Drive account, and the paid Proton plans add storage and other Proton services.

## Key features

- **End-to-end encryption by default:** Spreadsheets are encrypted on the device before upload, including metadata such as file names, so no one but the owner and invited collaborators can read them, not even Proton.
- **Real-time collaboration:** Edits from other people appear as they type, each collaborator has a named cursor, and notes can be attached to cells. Changes sync without a save step.
- **Sharing controls:** Share with specific people as Editor or Viewer, or create a public link with an optional password and expiration date. Access can be changed or revoked at any time.
- **Formulas, charts and data tools:** Built-in functions such as SUM and IF, bar, line and pie charts, conditional formatting, data validation and multiple tabs in one spreadsheet.
- **Import and export:** Imports CSV, TSV and XLSX files into a new or existing sheet and downloads spreadsheets as XLSX, CSV or TSV. ODS import and export were added in beta in February 2026.

## Good for

- People who want spreadsheets the provider itself cannot read
- Teams handling client or financial data under privacy requirements
- Existing Proton Drive users who want a spreadsheet in the same account

## Worth knowing

- There is no standalone Sheets plan; it is part of Proton Drive, and the paid plans differ in storage and bundled Proton services.
- In the Windows and macOS Drive apps a spreadsheet is only a placeholder file that opens in the browser at docs.proton.me.
- People invited by email need a Proton Account to open a shared spreadsheet; public links do not require one.
- The free plan's 5 GB of storage is shared with files, photos and documents kept in Proton Drive.
