REPOST FROM ANOTHER THREAD:
I'll echo the many before me; add a collab Spreadsheet appliance. I can forgo a PowerPoint type app, but having a spreadsheet is about all that's keeping me from jumping out of the Google airplane.

I absolutely need this. I have at least two spreadsheets of my own that I use at least every week or two, and 4 or 5 others that I use a little more sporadically. (For example: a sheet of our family's deductible medical expenses to track what we are eligible to withdraw from our Health Savings Account, I have a price list that calculates unit prices for me based on a vendor's CSV export, and a list of all my network devices with their MAC addresses and other info.)

Similar, but DO NOT HAVE ANY PART OF GOOGLE. There must not be one scrap of their code left.

plese merge with this idea > https://protonmail.uservoice.com/forums/945460-general-ideas/suggestions/48476849-please-add-a-spreadsheet-app

It would cut through a strong chain still bounding me to the Google ecosystem, if it will contain collaboration feature, for wich I could invite non-proton users. Much more important for me than the docs.

Daily spreadsheet user relying totally on Google Sheets. This would be a huge bonus!

We use a lot of spreadsheets and this would allow us to move off Google Sheets. Without this feature, we will probably move to CryptPad.

Docs is a good first step, but we need a sheets alternative.

We need this so badly! I'd literally cancel my Google One subscription if this is implemented.

Pleeeeeaaaasssseeeee!!!!!

I am trying to migrate some data gathering I do out of Google sheets and the lack of any even basic spreadsheet capability is a big barrier to do this. Having to make lots of edits over time means that downloading, editing, and re-uploading files is a very impractical alternative.

We must use Google Sheets for our business, so there's no way to get away from them until Proton has a comparable version. It's all I want. (Okay, I also want a good Photos service too.)

This is very important

Most of my work could be moved over to Proton sheets, with the option to export to Microsoft excel supported file so I can send it over to business who depend on Microsoft.

Many years ago, in the early days of online services, there was a set of applications ( calendar, spreadsheets, etc, all the google stuff) that you could run in your browser and they used storage provider of choice with it. If they are still around people could use that stuff with Proton Drive.

last piece before we can totally skip G-Suite

The only thing keeping my Google account alive at this point. Hoping to see this soon, and I think we will.

Spreadsheets with modern capabilities, I think it's important to point this out.

It would be of no use to me if the implemented sheet service is just something like SUM and INDEX/MATCH, when even LibreOffice has recently implemented some of Office 365/Google Sheet's functions: XLOOKUP, SEQUENCE, XMATCH, and so on.

I am new to Proton so forgive me. Am I correct in saying that I cannot access or edit my Microsoft Excel sheets stored on my Proton Drive from my Android phone, without having to download, edit and then upload again. If so this is not what they advertise on the website.

this is essential to transition my business email to proton
