PPTCompressOld workbooks, readable again
Excel 97-2003 files use the binary BIFF format. The converter reads it directly, sheet by sheet, so archived reports and exports from older systems can go straight into documentation or an AI chat.
- Each worksheet becomes a
## Sheet: namesection with one table - Dates come out as dates, true and false as TRUE and FALSE
- Formulas show the value Excel last calculated
- Very large sheets are cut at 20,000 rows, with a note saying so
Know the limits
Password-protected workbooks are refused. Charts, pictures, formatting and merged-cell layout are not carried over. The first row of each sheet is used as the table header, so a title row above the real column headings will show up as the header.

Questions
Do I need Excel to convert a .xls file?
No. The workbook is read on our server; you only need a browser.
What if my .xls is password-protected?
It is refused. Open it in Excel, remove the password, save and convert again.
Is it free?
Yes. Converting to Markdown is free and needs no account. Files up to 30 MB, with a fair-use limit of 30 files an hour per visitor.
Does it convert scanned documents?
No. The converter reads the text stored in the file. A scan or photo of a page has no text layer, so run OCR on it first.
Are images included?
No. The Markdown contains the text, headings, lists and tables. Pictures, charts and drawings are left out.
