Libreoffice is robust and the Collabora version has been deployed within Nextcloud for years. Could be a nice partnership with Collabora Productivity.

EPIC: As an user of Proton Drive, I'd like the ability to have a series of online collaboration tools (similar to Google Drive) so that I can create, store, and access documents on the cloud AND migrate off of Google Workspace.

User Story 1: As a Proton Drive user, I'd like the ability to have a cloud-based spreadsheet tool (similar to Google Sheets) so that I can manage spreadsheets online.

User Story 2: As a user of Proton Drive, I would like the ability to be able to store cloud based notes, tasks, or lists (similar to Google Keep, Microsoft OneNote, or Evernote) so I can use one tool to manage my dad-to-day task.

Huge opportunity into integrating LibreOffice into peoton drive

Agreed!

I would finally be able to get out of Google drive completely, if this was possible.

On this take I see more people where they would like a take of proton on spreadsheet, word and more. Where I think that would be great and bring loads of safety and security with it I would love to see when something like that gets added a update to proton drive. Where we can work directly on spreadsheets in the drive and maybe collaborate at the same time with other proton users?

Instead of making Proton Docs, Slides, etc. which take forever to make, just partner with a privacy based office suite like OnlyOffice to make everything easier.

How about OpenOffice?

For Proton Docs, and possibly sheets and slides, it would be a mess if Proton would bring multiple messy apps.
Instead, a lightweight and offline Office-Suit with basic (or Advanced) document editing features can simply suffice with multiple functions requested by most users.

My only gripe so far with it: It has no formatting what so ever. I would love to see it turn out as a better version of Liber Docs and or Docs. With how Proton does things... ittle defiantly be a lot better.

That or Libre Office YES!!!

I was just coming to comment this!!! It would make my decision to switch fully away from Microsoft much easier.

I look forward to new features deployed as indicated on your roadmap: https://proton.me/blog/proton-drive-product-roadmap

i agree with the idea, but it should be libreoffice

Proton has started making Proton Docs and that ecosystem which is great but the FOSS world already has the likes of LibreOffice and others. Integrating them into Proton would show Proton cares about FOSS but also gives Proton Users the option to use other open-source software right into Proton's Web UI.
Adding the option to open docs files in a web LibreOffice Editor would be amazing. I think Proton can and should build their own Docs and etc ecosystem but they should also integrate others that are FOSS, ethical and privacy minded.

This, but LibreOffice.

Please don't. The company and its development are based in russia, despite their claims to be based in Latvia

In order to use Proton Drive with big teams, we should be able to work simultaneously on docs as it happens with Google docs and the Office suite. Can you open Proton Drive to Office editors? Even the web version only would be a great added value compared to the current situation.
I would love to use my Proton Drive more but now the features are too limited for using it in bigger teams.

Good idea!
