What changes in the conversion
The download is a standalone HTML table with escaped cell text. It contains no scripts, links, images, or original workbook styling.
This is a values-only conversion. Formatting, merged cells, charts, images, comments, links, macros, and original metadata are removed. Formulas become saved results, which may be stale; missing results and error cells are rejected. Dates become ISO strings.

FAQ
What does XLS to HTML keep?

Are formulas calculated?
No. Only the last saved formula result is exported. Recalculate and save the file in Excel or LibreOffice before converting.
What happens to multiple worksheets?
