Proton Sheets

Open a new sheet, invite your teammate, and start typing—no second-guessing where your data ends up. Proton Sheets lets you co-edit budgets, project trackers, and content lists in the same tab while every change is saved to Proton Drive. Use roles to set who can view, comment, or edit. Name ranges, build formulas, add checkboxes and data validation, and track progress with filters. When a mistake slips in, jump to a previous revision to compare and restore without losing the thread.\n\nFor analysis work, pull numbers from your databases or BI stack. Connect a SQL source, paste a query, and bring results directly into a table that refreshes on a schedule. Clean messy columns with the AI Copilot, generate formulas from plain language, or ask for a quick summary of trends. Turn selections into charts to present KPIs or forecast scenarios, and save the layout as a template your team can reuse across clients or quarters.\n\nAutomate repetitive tasks to keep operations moving. Record a macro to import a CSV from Drive, normalize columns, apply formatting, build a pivot-style summary, and export a PDF—then run it daily with one click. Use conditional formatting to flag risks, assign owners with mentions, and keep discussions in the sheet with comments. For sensitive work like payroll, fundraising, or vendor pricing, restrict access by team and share with expiring links. Every share stays confined to your workspace, with no ad tech or trackers attached.\n\nWork anywhere. Open important files offline during travel, make edits, and sync when you reconnect. Live presence shows teammates’ cursors as they type; color-coded highlights prevent collisions. If a client needs view-only access, send a secure link; if a partner needs to model scenarios, grant edit rights temporarily and roll them back after. With sturdy version history, cloud storage, and encryption that keeps outsiders out, Proton Sheets fits day-to-day writing, planning, and number crunching without sacrificing control.
