How it works
- The SumSheet engine opens the workbook on one server of ours and reads every worksheet cell by cell. Formula cells go out as their computed values — the way Excel's own “Save as CSV” does — never as
=SUM(…)text. - One sheet gives you a .csv; several sheets give you a .zip with one CSV per sheet, named after the sheet. UTF-8 with a byte-order mark, comma-separated, quotes where needed — Excel, Google Sheets, pandas and databases read it as is.
- If a formula has no computed value in the file (a workbook saved without cached results), the page says how many cells that touched — before you download.
- Legacy .xls files: every sheet and every value comes out, but the engine does not yet apply their number formats — a date arrives as 43922, a percentage as 0.1594; the page says so. .ods is next: the engine still stalls on some multi-sheet ODS files, so it is not accepted yet.
- Nothing in the workbook is executed — no macro, no query, no connection — and after 24 hours the file and the CSV are gone.
Questions
- Which sheet becomes the CSV?
- All of them. A workbook with one sheet returns one .csv; with more, a .zip that holds one CSV per sheet, hidden sheets included and named after the sheet.
- Do formulas come out as formulas?
- No — as values, the way Excel exports CSV. Dates and numbers keep the format the cell shows. If some formula cells had no computed value stored in the file, the page tells you how many; they come out empty rather than as formula text.
- Is there a limit?
- 50 MB per file, about 600 000 cells in use across the workbook, and .xlsx/.xlsm/.xlsb/.xls today (.ods is next). The SumSheet app — free, for macOS, Windows, Linux, iPhone and Android — exports any size from the File menu, offline.
