Does my spreadsheet get uploaded?

No. The file is parsed in your browser. What leaves it: the column names, the detected type per column and up to five sample rows, capped at 200 characters per cell — enough for the model to understand the structure.

Both. .xlsx, .xls, .csv and .tsv. For Excel the first sheet is used; export the relevant sheet as CSV if it is not the first.

What if the sheet is fine as it is?

Then the analysis says so. Not every spreadsheet needs an app; the ones that do have several editors, statuses and permissions living in colours and habits.

Yes. No account, no card, no watermark. Each visitor can run a tool a few times an hour; the limit exists only to keep the tools fast for everyone.

What happens to what I type?

Your input is sent to an AI model to produce the result and kept with the result for 90 days so you can come back to it. It is not used to train anything, and result links are unlisted.

Can I use the result outside Chattee?

Of course. Copy it, download it, share the link. "Build this with Chattee" is there if you want the app built, not a condition.

How it works

upload_file

Drop the file

CSV or Excel. It is read in your browser; only the column names, detected types and up to five sample rows are sent.

table_view

See the structure

Which columns are really lookups, which are calculations, which belong to a separate entity — and who edits what.

apps

Get the app plan

Screens, roles, workflows and a migration step, plus a build prompt for the app that replaces the sheet.

Signs a spreadsheet wants to be an app

If two of these sound familiar, the analysis will be blunt.

group

Several people edit it

Conflicting versions, overwritten rows, "who changed this" — a database with accounts solves all three.

rule

Colours mean status

When a cell's colour carries information, the sheet has a workflow nobody wrote down. The app writes it down.

lock

Everyone sees everything

A sheet cannot show a row to one person and hide it from another. Roles and permissions can.
