Free editing / optional AI

Your creative workflow

Loading the local WebAssembly editor…

Open, edit, export

Use the editor’s native File menu. Save a local project or export before switching apps or closing this page. Automatic recovery and account sync are not promised. Confirm that the saved or exported file is available before closing; file handling varies by app.

Formulas and charts
PivotTables and workbook workflows

Bring a sample workbook, validate its key formulas, then compare a chart or summary with the original calculation.

AI when you choose

This editor does not upload documents to our AI service. Open AI Studio separately, then transfer compatible exported files manually. AI generation uses credits; editing here is free.

Open AI Studio ↗

New tab: your editor stays open.

Upstream documents XLSX read/write. Formula and layout fidelity are not guaranteed for every existing workbook.

Start with a copy of your file and test a small export. These are evolving upstream apps; browser features can differ from desktop releases. A loaded editor is not a guarantee of format compatibility.
