Excel isn't the problem. Everything around it is.
Nobody wastes time inside a spreadsheet. The time is lost around it: exporting CSVs, copy-pasting, refreshing by hand, emailing files back and forth.
Copy-paste
The same manual work, every day: copying data from a tool into a sheet. Every single time.
Stale data
The report is out of date the second you send it. The numbers have already moved at the source.
File chaos

You don't spend your time using Excel. You spend it maintaining it.
Connect your cells directly to your data.
Pick a source, point a cell at it. Updates arrive on their own — no more imports or exports.
Data becomes a native part of the sheet. You stop moving data around — the spreadsheet stays plugged into reality.
Know exactly where every number comes from.
Click a cell: a panel shows you its whole history. No more numbers nobody can explain.

No more mystery numbers.
Works even without internet.
Your data is cached on your machine. Cut the network: the spreadsheet keeps working, your numbers are still there. Sync resumes on its own when the connection returns.
On your machine
Your documents live locally. No waiting, no cloud dependency.
Cached data
The last known value stays available, even offline.
Automatic sync
As soon as the connection returns, everything updates, with no intervention.
Work together on the same data.
Share a sheet, comment on a cell, give the right rights to the right people — in real time, on data that's already up to date. All without ever uploading your workbook anywhere.
Sharing
Send the relevant sheet, not the whole workbook. With one link.
Comments & rights
Read, edit, per sheet or per range. Everyone sees what they should.
Real time
Multi-user co-editing, visible presence, on a single source of truth.
A live meeting, on a document that never leaves your machine.
Invite people into a live session, show your sheet updating before their eyes — and talk to each other, by voice. No Zoom, no Google, no upload: everything stays end-to-end encrypted, the cloud sees neither your data nor your voice.
1 · You invite
A link, or an email invite. They join from their browser, nothing to install.
2 · Waiting room
Nobody enters without your say-so. You see who's knocking and admit them with one click.
3 · Live + voice
Your guests watch the sheet move live, and you talk by voice — on a document that stays with you.
Free
Up to 3 guests, read-only live view + voice. Enough to show a dashboard and talk it through, right away.
Conference (paid)
More guests, live co-editing and conference sessions — still end-to-end encrypted, still on your machine.
Google Sheets keeps your document on Google's servers. YCell keeps it on yours.
