Spreadsheet AI: XLSX Editor

Edit real XLSX spreadsheets on your phone - with an AI copilot that never acts without your say-so.

Open workbooks from Files, email attachments, or any app that shares XLSX. Edit cells, formulas and formatting, then save back to the same file - what you didn't change stays exactly as it was, including features the app doesn't display yet.

AI copilot (you stay in control)
- Formula help - describe what you need, get a working formula with a plain-language explanation, inserted only when you tap Apply
- Explain - tap any formula and get it decoded in plain words
- Ask - question your data, get answers grounded in the sheet
- Describe it - describe a spreadsheet and get a ready-to-edit workbook
- Photo to sheet - photograph a printed table and turn it into an editable XLSX
Every AI result is a preview. Nothing is applied, and no sheet data leaves your device, without an explicit tap. AI usage includes a daily allowance, extendable with a short rewarded ad.
