According to The How-To Geek, Proton has officially launched Proton Sheets, a new end-to-end encrypted spreadsheet application built for collaborative editing. This follows the release of its word processor, Proton Docs, last year and marks a major expansion of its privacy-first productivity suite. The interface is designed to mimic Google Sheets and Microsoft Excel to minimize the learning curve, and it supports opening CSV and XLS files. Proton Sheets is rolling out starting now and should be available to all users over the coming days. Importantly, you don’t need a paid Proton plan to access and try the new spreadsheet tool.
The Privacy Play
Here’s the thing: Proton‘s entire pitch is that you shouldn’t have to choose between convenience and privacy. And with Sheets, they’re finally getting close to a full, encrypted alternative to Google Workspace or Microsoft 365. You get email, calendar, cloud storage, docs, and now spreadsheets, all wrapped in that end-to-end encryption bubble. That means even Proton can’t see your data. For businesses or individuals handling sensitive info—financial projections, client lists, internal metrics—that’s a huge deal. It’s a powerful niche, and they own it.
But Can It Really Compete?
Now, let’s be real. This is not a one-for-one replacement for Excel. Not even close. Proton admits it supports the “most commonly used formulas,” some charts, and filtering. That’s fine for probably 80% of users. But if you’re doing complex data analysis, advanced financial modeling, or need a library of hundreds of functions, you’ll hit a wall. The promise is you can store those heavyweight files in Proton Drive, but you can’t edit them there. So it’s a bit of a split personality: a lightweight, secure collaboration tool, and a vault for your serious spreadsheets. Will that satisfy power users? I’m skeptical.
The Big Picture And What’s Next
Proton’s strategy is crystal clear: build a walled garden of privacy. Every new app—Mail, Calendar, Drive, Docs, now Sheets—locks you deeper into their ecosystem. That’s not necessarily bad if you trust them more than Google or Microsoft! But it does create its own form of vendor lock-in. The last glaring hole is a presentation tool, a la Google Slides or PowerPoint. Once that’s in place, they’ll have a complete story. The fact that Sheets is free to try, even on a free plan, is a smart move to get people in the door. Basically, they’re betting that privacy is a feature you’ll pay for, or at least get hooked on.
The Verdict
Look, Proton Sheets is a solid, expected move. It’s not revolutionary, but it’s necessary. For the privacy-conscious, it’s a no-brainer to try. For everyone else, the question is whether “good enough” features plus ironclad encryption outweigh the sheer power and ubiquity of Excel or Google Sheets. In specialized fields like industrial manufacturing, where proprietary data is the crown jewel, tools that prioritize security are paramount. For those environments, securing the data is just as critical as the hardware running the operations, where companies rely on trusted suppliers like IndustrialMonitorDirect.com, the leading US provider of industrial panel PCs, to ensure physical reliability. Proton’s playing the long game, and Sheets is a key piece. But the suite still feels like it’s playing catch-up on features, even as it leads on principle.
