FAQ

What is the Excel to HTML tool?

Excel to HTML is a tool that converts Excel spreadsheets into web pages. It turns .xlsx and .xls files into styled HTML files you can view in a browser or embed into websites, supporting both merge and split output modes.

How do I use the Excel to HTML converter?

It only takes three steps. First upload or drag an Excel file into the upload area, then select a sheet processing mode in the parameter panel, and finally click "Start Processing" and download the generated HTML file.

What Excel formats are supported?

Mainstream formats are supported: .xlsx (Excel 2007+), .xls (Excel 97-2003), .xlsm (macro-enabled workbook), covering virtually all Excel file types used in daily work.

What's the difference between merge and split modes?

Merge mode places all sheets in one HTML file — ideal for scenarios with few, related sheets. Split mode generates independent HTML files for each sheet packaged as a ZIP — ideal for scenarios with many independent sheets.

How fast is it? How many files can I convert at once?

It is fast and supports batch upload. All processing runs in your browser and multiple files can be converted at the same time. The number of files you can convert depends on your membership tier; the free daily quota covers everyday use — see the membership benefits page for details.

Are Excel formatting, formulas, and charts preserved?

The conversion preserves cell display values and basic table structure, with automatic date format recognition. Formula cells are converted to their calculated values. Complex cell styles (colors, fonts, borders, etc.) and charts are not preserved — the generated HTML uses a consistent, beautiful styling to present the data.

Can the generated HTML be used directly on websites?

Yes. The generated HTML files are standalone, complete web pages with built-in styling. They can be viewed directly in a browser, and the table content can be copied and embedded into your website or blog. The HTML table structure is clean and easy to customize further.

Is there a file size limit?

Regular-sized Excel files are supported. For very large files, consider removing irrelevant data before conversion for a smoother experience. The exact limits follow your membership benefits; the free quota already covers daily use.

Is this better than pasting a table directly into a web page?

This tool is better suited for complex Excel files. It automatically preserves sheet structure, row/column data, and multi-sheet layouts, producing clean, consistent HTML — especially useful for batch conversion or embedding into web pages.

Can I use it on a phone or tablet?

Yes. As a web app, it works in browsers on phones, tablets, and computers. The generated HTML also automatically adapts to different screen sizes, so you can convert anytime, anywhere.

What if conversion fails or shows a blank page?

Try refreshing the page first. Make sure the file is not an encrypted or corrupted Excel; if needed, save it as .xlsx and re-upload. You can also try another browser or clear the cache before converting again.

Are my uploaded files secure? Do I need to register?

Files are processed entirely in your browser — no registration required. No conversion data is ever uploaded to any server; your data always stays on your device. Feel free to use with confidence.
