Extract spreadsheet formulasList every formula in a workbook with its sheet and cell, to audit or document it. Reads Excel (XLSX, XLSM), OpenDocument (ODS) and Apple Numbers, in any language — a French SI() or a German WENN() comes out as written. XLS and XLSB carry formulas that this reader cannot always surface, and CSV or TSV hold none by design: they store results, never formulas.EML viewerOpen a saved email and read it — sender, date, subject and body — with no mail client.ICS viewerOpen a calendar invitation or export and read its events before importing anything.MBOX viewerList every message in an mbox export — sender, date and subject — without a mail client.VCF viewerOpen a .vcf file and read the contacts it holds, without importing them anywhere.CSV to ExcelConvert a CSV file (or pasted CSV) into a real .xlsx spreadsheet.Excel to CSVConvert an .xlsx or .xls sheet to CSV, pick which sheet.Convert formulas to valuesReplaces every formula by the result Excel last saved with it, so the sheet keeps its numbers but no longer shows how they were obtained — useful before sending a file out. Nothing is recalculated: a workbook saved without cached results comes back empty. Works with Excel (XLSX, XLS, XLSM, XLSB), OpenDocument (ODS), Apple Numbers, CSV and TSV — though CSV and TSV never hold formulas to begin with.

Frequently asked questions

What is Spreadsheet viewer?

Open and read an .xlsx, .xls, .ods or Numbers file without a spreadsheet program.

When would I actually use this?

Getting a table out of a workbook and into something else — JSON for an API, CSV for an import, HTML for a page — opening a file whose software you do not have, and cleaning a sheet before you hand it on.

What is the most common mistake?

Expecting the formula to survive the trip. A converted file carries the last value the spreadsheet computed, not the calculation behind it — and a workbook written by a program can carry the formula with no cached value at all, which most readers discard along with the cell.

How is Spreadsheet viewer different from Extract spreadsheet formulas?

They sit next to each other but answer different questions. Extract spreadsheet formulas: list every formula in a workbook with its sheet and cell, to audit or document it. Reads Excel (XLSX, XLSM), OpenDocument (ODS) and Apple Numbers, in any language — a French SI() or a German WENN() comes out as written. XLS and XLSB carry formulas that this reader cannot always surface, and CSV or TSV hold none by design: they store results, never formulas. Pick whichever matches what you're starting from — both are free.

Where do the figures come from?

Nothing leaves the browser. An .xlsx and an .ods are both zipped XML, read here against their published specifications. Dates are the fragile part — a spreadsheet date is a number counted from an epoch the workbook itself declares, so the same 45000 is two different days depending on a flag most files never show you.

ExplainerThe Workbook with Twenty-Three Formulas That Reported NoneA cell can hold a formula and no cached result. A reader that skips empty cells throws the formula away with them — and says the file has none. One parsing option separates the two cases.ExplainerConverting Formulas to Values Keeps the Cached Answer, Not the CalculationA spreadsheet file stores both the formula and the last answer Excel computed. Stripping the formula leaves the stored answer — and leaves a blank wherever the file never carried one.How-toOne File per Tab, and What a Split Leaves BehindSplitting a workbook writes one .xlsx per sheet, named after the tab. It carries the values across and not the formulas — which is the right default when the point is to send one department its own tab.ExplainerThe .ods File That Is Valid, and That Your Reader RefusesOpenDocument makes styles.xml optional. Several readers demand it and reject the whole document without it — "Cannot find file styles.xml in zip" on a file that is not broken.ExplainerA Cell of Three Spaces Counts as Empty, and That Is the PointWhitespace is the whole reason these tools exist. A row of blanks looks empty, is not empty to a strict test, and quietly survives every filter you apply after it.How-toMerging Workbooks: One Sheet Each, or One Table for AllTwelve monthly reports can become twelve tabs or one table of twelve months. Only the second can be sorted and summed in one go — and it is the one where the header rows need handling.
