SumSheet opens and edits Excel spreadsheets on your device. 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 β€” 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 β€’ Opens .xlsx, .xlsm, .xlsb, .xltx and .xltm β€” from the Files app, mail, or any app’s β€œOpen in…” β€’ Edits cells in the formula bar and recalculates formulas β€” across sheets too β€’ 200 worksheet functions: math, text, dates, lookup, logical, financial, engineering β€’ Tables with filters, conditional formatting, number formats, charts β€” kept as in the file β€’ Keeps the workbook structure intact β€” 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.
