definitely need this feature, i would also add the sheet dose not need to be like excel or in google sheet, i would like to suggest to use some features from coda, the table functionality really good fun to use

Spreadsheet function (real time, collaborative, calculation and table creation) is necessary, and the only thing holding me back from converting to Proton.

Secure Notes and Photos also a big priority.

Absolutely! Proton Docs is a solid start for document editing, but to be truly competitive, adding Proton Sheets and Proton Slides would make it a full productivity suite.

Here are the key improvements needed:

Proton Sheets: A spreadsheet app with formulas, charts, and data analysis features.

Proton Slides: A slideshow app for presentations with animations, templates, and multimedia support.

Enhanced Docs features: Ability to move, resize, and layer images; better formatting options; collaborative editing improvements.

These additions would make Proton Docs a full alternative to Google Workspace or Microsoft 365 while keeping Proton’s privacy focus.

EDIT:
Proton Sheets support page got launched, there are no articles.
https://proton.me/support/drive/sheets
Also, the logo got revealed in GitHub: https://github.com/ProtonMail/WebClients/blob/main/applications/docs/src/app/hooks/sheets-favicon.svg

And while you're at it, allow to use Alias's in the various shared documents, last time I checked you automatically doxed your user acc with every shared doc

A real misstep in a "privacy focused company"

in regards to notes proton pass does have secure notes, but a proper alternative to onenote or google notes that can be shared for group notes would be really useful

Update: Sync with Google Drive via Easy Switch and piggyback off their Sheets for the time being?

Comment how you feel about this.

Until they make their own Sheets.

I would also love to see a simple, secure replacement for OneNote. I use OneNote a lot but an concerned about the privacy of my notes.

When implementing this feature it is also important that proton supports all office documents; As not all documents should be opened in a web browser. (e.g. a word document can still be opened in word and I dont have to use multiple different tools and programs just to edit a single line in my document, or change my document when I sync it and fear it might not work on other devices)

To complete a truly independent, privacy‑first digital life, I’m missing three key productivity tools that are currently only available from US‑based providers:
1. ProtonCalc – a web‑based spreadsheet editor (compatible with Excel/Google Sheets formats) that stores files in Proton Drive. I would use it for personal budgeting, expense tracking and simple data analysis.
2. ProtonPresent – a lightweight presentation builder that lets me create and deliver slide decks stored in Proton Drive.
3. ProtonPhoto – an integrated photo/video hub within Proton Drive that automatically syncs media from my phone and offers basic editing/organising tools.

Having these three capabilities would allow me to retire both my Google account and Microsoft 365 subscription entirely, consolidating all my personal data under Proton’s umbrella.

I really miss spreadsheet in my Drive app.

In order to really move away from Google, we need a real-time collaborative spreadsheet option. I have fully moved away from Google except for work, where I can't recommend an alternative to Google Sheets, so we continue to use it.

The only feature keeping me from leaving Google entirely. Don't need slides, just sheets please!

I'm assuming sheets can be used by everyone and should come first. I never have a need for slides tho

Hello, I want to collect data from potential clients, speakers etc. A critical tool that I'm trying to replace is Google Forms. I would love a Proton alternative 🙏

The only reason that I do NOT in any way use Proton Drive (which I really want to do, to get away from Google completely!) is because it has no spreadsheet feature. Please add this essential feature.

Even adding spreadsheets to Drive would make this product hugely more attractive to new users.
You don't need to implement fancy stuff right away, like non-integer optimization.

How can you have an office suite without spreadsheets?

u should be able to use libreoffice, which is foss and wouldnt be proprietary behind a even higher sub cost.

I disagree completely making this a thing for Proton.

Please, this is probably by far and above the single most important feature that can possibly be added into the Proton ecosystem. Google is quickly evolving into a truly sinister company and yet the power and convenience of their docs/sheets/slides/etc makes it hard to not continue using them.

I've been using Proton since the beginning and am a Visionary account holder, and this is the last missing element for me that would spur me to fully delete my google account and only use Proton for everything. Thank you, I seriously hope this can be done sooner than later.
