Named after the most famous formula on the planet, SumSheet runs on the same native XLSX engine that powers SumOffice on the desktop and on the server — so a workbook calculates the same wherever you open it. Change a price and the total recalculates, exactly as it would on a laptop.
WHAT IT DOES
• Opens .xlsx, .xlsm, .xlsb, .xltx and .xltm — from the Files app, mail, or any app’s “Open in…”
• Edits cells in the formula bar and recalculates formulas — across sheets too
• 200 worksheet functions: math, text, dates, lookup, logical, financial, engineering
• Tables with filters, conditional formatting, number formats, charts — kept as in the file
• Keeps the workbook structure intact — sheets, formats, formulas, macros stay in the file
YOUR FILES STAY YOURS
Editing happens on the device. Workbooks are not uploaded anywhere, and the app does not require an account to open a file.
PART OF SUMOFFICE
SumOffice is an office suite built around one document engine: the same logic in a desktop application, inside your own product, on a server, and here on the phone. SumDoc is its document counterpart.
SumOffice is an independent product and is not affiliated with Microsoft.
