Good to know
- The XLS file is opened by LibreOffice, not by Microsoft Office. Text, tables, pictures and ordinary charts convert accurately; effects such as SmartArt, animations, some chart styles and fonts LibreOffice does not have can look different from Office, so check a complex file before relying on it.
- Every sheet is in the one HTML file, with its pictures built into it.
Frequently asked questions
Is converting XLS to HTML free?
Yes. Everyone gets 25 free credits a day, with no account needed. Conversions on our server use one credit per started minute of work, so most cost a single credit. Credits reset at midnight UTC.
Are my XLS files uploaded anywhere?
This conversion runs on our server, because reading an XLS file needs LibreOffice, which does not run in a browser. Your file is sent over an encrypted connection, and both it and the result are deleted 72 hours after the conversion. The server has no internet access while it works on your file.
How large can the XLS file be?
Up to 1 GB per file. This conversion runs on our server, which accepts files up to that size.
Will the HTML look the same as the XLS?
The text and structure are kept: headings, lists, tables, bold and italic. Exact page layout, fonts and spacing may differ, because HTML is flowing text, not fixed pages.
Can I convert several XLS files at once?
Yes. Add as many files as you like; they are converted one after another, and each one gets its own Download button.
