About the XLS to HTML Converter
Need to turn a XLS file into HTML? This free converter changes XLS spreadsheets into HTML in a few seconds, right in your browser. People usually convert because XLS is a legacy format limited to 65,536 rows, while HTML gives you a self-contained web page. HTML files open in every web browser, VS Code, Dreamweaver, WordPress and email builders.
Spreadsheets are read and written with SheetJS, the open-source spreadsheet engine used by thousands of data apps, so every sheet, row and value is handled accurately. Because everything happens on your own device, your spreadsheets are never uploaded, stored or seen by anyone else, which makes it safe for customer lists, salary sheets, GST data and API exports.
What to expect: every sheet in the workbook is converted; formulas are exported as their calculated values, while text such as PIN codes and phone numbers with leading zeros stays intact; the first row is used as column names, which you can switch off.
How to use the XLS to HTML Converter
- Click "Choose files" or drag your XLS spreadsheets onto the box. You can add several at once.
- Choose whether the first row holds column names and whether to convert all sheets or only the first.
- Press "Convert to HTML". The conversion runs on your device and shows its progress.
- Download each HTML file, or use "Download all (ZIP)" when you converted several.
- Open the result in every web browser or VS Code to check it; your original XLS is never changed.
Tips & benchmarks
- The HTML file is self-contained with clean, readable markup and simple styling, and images are embedded inside it.
- Merged cells are unmerged and their value is kept in the first cell, which keeps the data easy to filter and import.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the HTML to a website or government portal.
Frequently asked questions
How do I convert XLS to HTML?
Click "Choose files", select your XLS spreadsheets, adjust the options if you want, and press "Convert to HTML". The HTML downloads immediately; with several files you can download everything as one ZIP.
Is this XLS to HTML converter free and safe?
Yes. It is completely free, with no sign-up, no daily limit and no watermark. The conversion runs inside your browser, so your spreadsheets never leave your phone or computer and nothing is stored on News Appite's servers.
Are formulas, formatting and all sheets kept?
Every sheet is converted (or only the first, if you choose). Formulas are exported as their current values, and cell colours and fonts are not carried over because formats such as CSV, JSON and SQL cannot store them.

What is the difference between XLS and HTML?
XLS (Microsoft Excel 97–2003 Workbook) is a legacy binary spreadsheet best suited to older Excel versions, legacy ERP and bank systems and portals that only accept .xls. HTML (HyperText Markup Language) is a web page markup best suited to publishing on the web, email newsletters and viewing documents in a browser.
Is there a file size limit?
There is no upload limit, because nothing is uploaded. The practical limit is your device's memory: files of a few hundred megabytes work on most computers, and phones handle smaller files comfortably.
