How to convert XLS to HTML

  1. Add your XLS spreadsheets

    Drop XLS files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.

  2. HTML is already chosen

    Press Convert. There is nothing else to set. The work happens in this tab.

  3. Download

    Save the HTML, or download everything as one ZIP if you converted several files.

Why ToAny

  • Private by construction

    The XLS to HTML converter is part of this page and runs inside your browser. Your spreadsheets are never sent to ToAny or to anyone else.

  • No upload, no queue

    Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.

  • Free, without an account

    No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.

XLS to HTML: what to expect

XLS is limited to 65,536 rows and is flagged as a legacy format by modern Excel. HTML opens in any browser and can be published on the web as-is. XLS is at home in compatibility with very old copies of Excel; HTML is the usual choice for web pages and emails.

Formulas come across as the values they last calculated, and formatting such as colours and column widths is not carried over. The table is written as an HTML table in a complete page you can open or paste into a document.

Web page

HTML is the markup every web page is written in. A saved .html file contains the page's structure and text; its images, styles and scripts usually live in separate files.

Questions

Are my spreadsheets uploaded anywhere?

No. The XLS to HTML conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.

Is anything lost when converting XLS to HTML?

The content is carried over as faithfully as HTML allows; features that HTML does not have are left out.

Can I convert several XLS files at once?

Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.

How do I convert XLS to HTML on Windows, Mac, iPhone or Android?

The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the XLS file, press Convert and save the HTML. There is nothing to install.

Is there a file size limit?

Yes. Spreadsheet files up to 150 MB are accepted; a larger file is refused with a message. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
