How do I convert an XLSX spreadsheet to an EPUB e-book on LetsConvert?

Upload your XLSX file, choose EPUB as the target format, and click Convert. After processing, download the EPUB. Each sheet becomes a chapter; cell values and visible formatting are rendered as HTML tables, with line breaks for empty rows.

Why would anyone want to convert XLSX to EPUB?

XLSX is for data manipulation, EPUB is for reading. Converting XLSX to EPUB turns spreadsheet data into a portable, reflowable document—ideal for publishing tables, logs, or catalogs as e-books on tablets and e-readers, and it reduces file size by stripping formulas and macros.
