Proton Sheets

Open a new sheet and get straight to work, knowing only the people you choose can see it. Create a budget, roadmap, or roster inside Proton Sheets, then invite teammates as viewers or editors. Collaborators type alongside you in real time, and you can watch changes appear cell by cell. Lock down sensitive tabs with access rules, limit who can edit formulas, and keep stakeholders to view-only. If something goes off track, roll back with version history to any prior state, compare differences, and continue without losing context.

Turn raw information into decisions with a focused data workflow. Import CSVs, pull rows from an SQL source, or link a BI connector to refresh key metrics. Use filters, pivots, and quick charts to surface trends, then assemble a lightweight dashboard for weekly check-ins. Build repeatable steps with macros: reconcile monthly expenses, reformat incoming exports, or auto-clean columns in a click. Traveling or on-site? Switch to offline mode to review or update figures without a connection; everything syncs securely once you’re back online.

Move faster on planning and content operations with ready-made templates. Spin up an editorial calendar, sprint tracker, or OKR sheet and tailor it to your workflow. Assign owners, set due dates, and track status with simple visual cues. Share securely with leadership or external partners: send a view-only link or add them as a restricted collaborator so they can follow progress without altering your work. Keep related files together by organizing sheets inside your Proton Drive folders, so briefs, assets, and reports live in one protected workspace.

Let AI Copilot take care of the busywork while you focus on outcomes. Ask it to write a complex formula, explain an error, summarize a quarter’s results, or generate a starter dashboard from your data. Record a routine and Copilot can turn it into a reusable macro, saving clicks across your team. Throughout, your spreadsheets are end-to-end encrypted, so even Proton can’t read them. No matter if you’re modeling cash flow, planning a launch, or handling private research, you work the same way you always do—only with tight control, clear history, and security built in.
