Proton Sheets is currently missing a basic, foundational spreadsheet feature that has existed in Excel and Google Sheets for well over a decade: internal hyperlinks between sheets in the same spreadsheet.

Right now, it is not possible to create a clickable link in one sheet that navigates to another sheet within the same file.

Let me be absolutely clear about why this is a serious problem:

I routinely work with large, complex spreadsheets containing dozens to hundreds of sheets. These are not “toy” spreadsheets. They are operational frameworks, logs, dashboards, and documentation systems that must live inside a single file.

In every competent spreadsheet environment (Excel, Google Sheets), this is solved with:

Sheet-to-sheet hyperlinks

Clickable navigation menus

Index / contents sheets that actually work

In Proton Sheets:

You cannot right-click a cell and link to another sheet

You cannot create an internal anchor link

You cannot build a navigable index

You are forced to scroll horizontally through endless sheet tabs like it’s 2003

That is not a workaround. That is a product failure.

Suggesting that users “just click the tabs at the bottom” is not realistic once a spreadsheet scales beyond a handful of sheets. When you are dealing with 50, 100, or 200 sheets, manual tab-hunting is slow, error-prone, and frankly absurd.

This feature is:

Not advanced

Not niche

Not optional

It is table-stakes spreadsheet functionality.

The fact that Proton Sheets shipped without internal sheet hyperlinks strongly suggests it was designed for very small, very simple spreadsheets, not real-world operational use. That puts it far behind Google Sheets and Excel in practical terms, regardless of privacy advantages.

Feature request (non-negotiable):

Ability to create hyperlinks that navigate to another sheet within the same spreadsheet

Ideally with support for targeting a specific cell (e.g. SheetX!A1)

UI support via right-click “Insert link” or formula-based linking

Until this exists, Proton Sheets is not viable for serious spreadsheet users running large, multi-sheet systems.

I want to use Proton’s ecosystem. I am actively trying to move away from Google. But missing fundamentals like this make that impossible.

Please prioritise this. It should have been there from day one.
