  • 7× fewer tokens per taskThe agent reads one formula and the range it covers, not a million cells, and walks every precedent on a live engine. Measured against a bare harness on the same SpreadsheetBench tasks.
  • Human and agent collaborationThe agent highlights a range and asks you a question in the sheet. You answer by editing. Every change is in the action log and reversible.
  • Top scores on SpreadsheetBench97% on the SpreadsheetBench verified-400 set, with 7× fewer tokens per task than an agent reading the file with Python.

What happens when a license lapses

Files always open, edit and save, on every tier, forever.

  • For Apps: The grid shows a watermark and exports gain a notice sheet.
  • For Servers: Calculation, export and scripts stop, with a message that names the fix. Nothing else does.
  • For Agents, Pro: Returns to Free and its daily run limit.

Questions

Is the engine open source?

The UI and the agent skills are MIT. The engine is free to evaluate, watermarked outside localhost, and licensed for production. See which packages are open source.

Do I need a Developer license and an App license?

An App license is what you need to ship, and your first ten developers are free with it, counted once across all your licenses. Add Developer licenses only from the eleventh, or to build before you have an app to ship.

What counts as an app?

One product under one signing authority, such as a domain, a bundle ID or an Electron app. Subdomains, staging and QA count as the same app. A second product is a second app. The EULA has the full definition.

Can I use SheetXL for Agents at work for free?

Yes. Free has a daily allowance of agent runs, lifted during launch. Pro removes it for good. Teams that want central licenses take Business.

Does SheetXL send my data anywhere?

Never your workbooks. Free and Pro send usage stats to SheetXL. Business turns that off or routes it to your own audit endpoint.

What is an agent run?

One script your agent executes against a workbook, however many cells it touches. Opening, editing and saving a file is never a run.

Can I run it air-gapped?

Yes. Enterprise licenses come with an offline-signed key, so nothing needs to reach SheetXL to validate.

What happens when Founder Circle ends?

Nothing, for you. The rate you bought at is locked in for life on that license; later prices apply only to new licenses. To change products or add licenses, write to sales and we carry your rate across. Write to sales.

Got a question we didn't answer?

Licensing, procurement, anything on this page. A person replies, usually within a day.
