Convert Excel or CSV to an HTML Table

Turn an Excel workbook or CSV file into a ready-to-paste HTML <table> right in your browser. This free Excel to HTML converter reads your .xlsx, .xls or .csv file locally with SheetJS, lets you pick the sheet you want, and builds clean HTML you can copy or download as a .html file. A live preview shows exactly how the table will render, and you can strip the inline id attributes for tidier markup. Whether you need to convert a spreadsheet to HTML for a webpage, email template or CMS, everything happens on your device. Your file is never uploaded — the entire conversion runs 100% in your browser.

Frequently asked questions

What file formats can I convert to an HTML table?

You can convert Excel workbooks (.xlsx and .xls) as well as CSV files. The tool reads them with SheetJS and outputs a standard HTML <table> you can paste anywhere.

Is my spreadsheet uploaded to a server?

No. Your file is read and converted entirely in your browser, so your Excel or CSV data never leaves your device and nothing is uploaded to any server.

Can I convert a workbook with multiple sheets?

Yes. When a workbook has more than one sheet, a dropdown lets you pick which sheet to convert. Convert each sheet one at a time and copy or download them separately.

What does the Clean HTML option do?

SheetJS adds an id attribute to every cell. With Clean HTML checked, those id attributes are removed so the markup is shorter and easier to style; uncheck it if you want to keep them.

How do I use the HTML table once it is generated?

Click Copy to copy the raw HTML into any webpage, email template or CMS, or click Download to save it as a standalone .html file you can open or edit.

Is there a file size or row limit?

There is no fixed limit set by the tool. Because everything runs in your browser, very large spreadsheets depend on your device's memory, but typical files convert instantly.
