Compare Proton Sheets vs. Proton Mail

Proton Sheets is a privacy-centric spreadsheet application seamlessly integrated into Proton Drive's encrypted cloud workspace, enabling users to create, modify, and collaborate on spreadsheets while ensuring that all data remains fully end-to-end encrypted, so that only those with permission can view the information, protecting sensitive data from surveillance, data harvesting, or AI training. Users can initiate a new spreadsheet directly in Proton Drive, easily import files from formats like CSV, XLS, or Excel, and arrange their data across various tabs using standard spreadsheet functionalities, including built-in formulas such as SUM and IF, along with features like conditional formatting, sorting, and visualizations through charts and graphs for effective tracking of budgets or project planning. With real-time collaboration capabilities, users can edit together live and manage access permissions, ensuring that they maintain control over who can view or alter their documents, while also keeping a secure version history of changes made. This comprehensive tool not only enhances productivity but also prioritizes user privacy, making it a valuable resource for anyone needing to handle sensitive information securely.
