Connect Excel

Upload a workbook or connect OneDrive. Nothing leaves your control.

02

AI understands

Excelfyio discovers the schema, profiles data, and learns the business.

03

Cloud or Desktop

Choose application generation in the cloud, or native intelligence on Windows.

04

Generate & deploy

Ship insights, dashboards, and applications — or stabilize in place.

Excel already runs your business.Now it can understand it.
