About Excel Info

Excel Info opens an .xlsx or .xls workbook and reports its structure without you having to load it into Excel: sheet names, the row and column count of each, and a preview of the data. Reach for it when you receive a spreadsheet from someone else and want to know what's inside before committing to a conversion or import. It reads the file in your browser, so nothing is sent to a server.

Common uses

  • Confirm which tabs a vendor's workbook actually contains before wiring it into an import pipeline
  • Check a sheet's row count to estimate how long a downstream conversion or load will take
  • Spot an unexpectedly empty or single-row sheet that would otherwise break a parser
  • Preview the first rows to verify the header row is where you expect before mapping columns
  • Audit a batch of received workbooks for consistent sheet naming
  • Decide whether to use Excel to CSV, Excel to JSON, or Split Sheets based on what's really in the file

Frequently asked questions

Which Excel formats can it read?

Both modern .xlsx (OpenXML) and legacy .xls (BIFF) workbooks are supported.

What exactly does the report contain?

A JSON summary listing every sheet name, its row and column counts, and a short preview of the cell data.

Does it change my file?

No. It is read-only inspection — your workbook is never modified, and it isn't uploaded anywhere.

Will it show formulas or just values?

It surfaces the cell data as read from the workbook; the preview reflects values present in the sheet, not a recalculation engine.

Can it handle a workbook with many sheets?

Yes — every sheet is enumerated, so a workbook with dozens of tabs is reported in full.
