Proton Sheets vs Google Sheets: Privacy-Focused Excel Alternative Revealed! (2026)

Your data is under siege, and the culprits might surprise you. Every time you open a spreadsheet, you could be feeding Big Tech’s insatiable appetite for your information. But here’s where it gets controversial: Proton, the privacy-focused tech company, is challenging this status quo with its latest offering—Proton Sheets. After five years of developing secure alternatives to Google’s productivity apps, Proton is now taking aim at Google Sheets and Microsoft Excel with a tool that promises to keep your data locked down tighter than Fort Knox.

Proton Sheets isn’t just another spreadsheet app; it’s a fortress for your data. End-to-end encryption is the default here, meaning not even Proton can peek at your numbers. This is a game-changer for businesses that handle sensitive information, but it’s equally powerful for individuals who value their privacy. Whether you’re managing budgets, tracking projects, or analyzing data, Proton Sheets ensures your work stays yours and yours alone.

But this is the part most people miss: Proton Sheets isn’t just about security—it’s also about functionality. The app comes packed with features you’d expect from industry leaders, like chart-building tools, advanced formulas, and seamless file importing and exporting (think CSV, XLS, and more). Plus, collaboration is a breeze. You can share spreadsheets with other Proton users and control access with just a few clicks, adding or removing collaborators as needed.

Avant Vijay Singh, Head of Product at Proton Drive, puts it bluntly: “Big Tech’s business model is built on exploiting your data. With AI now in the mix, every keystroke you make could be training their algorithms.” He argues that this is an unacceptable trade-off and that users deserve better. Proton Sheets is their answer—a tool that combines privacy with power, giving you the freedom to work without hidden surveillance or invasive data mining.

Here’s the kicker: Proton Sheets is free if you already have a Proton Drive account. The free tier includes 5GB of storage, and paid plans scale up to a whopping 3TB. This positions Proton not just as a competitor to Google Sheets, but as a full-fledged rival to Google’s entire productivity suite. With Proton Sheets joining the ranks of Proton Calendar, Docs, Drive, Mail, VPN, and even PCMag’s top pick for a free password manager (Proton Pass), the company is building an ecosystem where privacy isn’t an afterthought—it’s the foundation.

But here’s the controversial question: Can Proton truly dethrone the giants of Big Tech? While Google and Microsoft have the advantage of brand recognition and deep integration, Proton’s focus on privacy could be its secret weapon in an era where data breaches and surveillance are daily headlines. What do you think? Is privacy worth switching to a new platform, or is the convenience of Big Tech too hard to give up? Let’s debate in the comments—your take could spark the next big conversation.
