How to Convert Excel to HTML Online
- Drop one or more .xlsx or .xlsm workbooks — everything is processed locally and never uploaded.
- Click Convert to HTML — every worksheet is rendered as a proper HTML table.
- Check the preview — each result row shows the generated HTML before you download.
- Download the .html file — a single file downloads directly; multiple files come back as a ZIP.
What the Output Page Looks Like
The result is one complete HTML document: a UTF-8 meta tag, a title taken from the file name, a small embedded stylesheet with collapsed borders and cell padding, and one "<h2>SheetName</h2>" section with a <table> per worksheet. Because the styling is inline, the file renders the same everywhere with no external dependencies.
The page is plain, static HTML — no JavaScript, no tracking, no external assets. It is safe to email, embed or archive as-is.
Output Rules at a Glance
| Content in Excel | HTML output |
|---|---|
| Each worksheet | An <h2> heading plus one <table> |
| Cell text and numbers | Table cells as plain text |
| Line break inside a cell | A <br> inside the cell |
| Formula cell | Its last calculated value |
| Styles, colors, merged cells | Not carried over — the embedded stylesheet applies to all tables |
Compared with Other Export Routes
| Method | Where your file goes | Notes |
|---|---|---|
| This tool | Nowhere — your browser | Free, batch support, one tidy self-contained page |
| Excel’s own Save as Web Page | Stays local | Produces heavy, legacy markup full of Office-specific code |
| Typical online converters | Uploaded to third-party servers | Often wrap output in ads or limit file size |
Limitations
- .xlsx and .xlsm only — convert legacy .xls files to the new format first.
- Cell colors, fonts and merged ranges have no representation in this output.
- Very large sheets produce very large HTML — consider converting sheet by sheet.
- The output is static: editing the table requires editing the HTML or the source workbook.
Frequently Asked Questions
Is this Excel to HTML converter free?
Yes — 100% free with no sign-up, no watermark and no file limit. All conversion happens in your browser.
What exactly does the output contain?
One complete HTML document with a UTF-8 charset, a title from the file name, an embedded stylesheet, and an <h2> plus <table> for every worksheet.
Can I publish the file directly on my website?
Yes. The output is self-contained static HTML with no scripts or external assets — paste it into a CMS, attach it to a page, or open it locally.
How are multiple sheets handled?
Each sheet gets its own <h2> heading and table, in the same order as in the workbook.
Are formulas converted?
Formulas are exported as their last calculated values — static HTML has no formula concept.
Will my file be uploaded to a server?
No. The workbook is opened, converted and previewed entirely in your browser with JavaScript. Your file never leaves your device.
Can I convert several workbooks at once?
Yes. Drop multiple files and download the .html results together as a single ZIP archive.
Does the table keep cell colors and fonts?
No. The output uses one clean shared stylesheet; cell-level styling is intentionally simplified away.
