Free Excel (XLSX) to XML converter

Why convert XLSX to XML?

People convert XLSX to XML because an XLSX needs a spreadsheet program, and plenty of systems accept nothing but plain text, while XML is what enterprise systems, feeds and older APIs still demand.

How to convert XLSX to XML

1. Choose your XLSX file. Drop it on the box above, or tap to browse. You can pick several files at once.
2. Confirm the target is .xml. It is preselected when your browser can encode it; otherwise the closest available target is chosen. Adjust quality, size or the other options if you want to.
3. Convert and download. Press Convert, then Download. Your file stays on your device the whole time.

What is a .xlsx file?

XLSX is the modern Excel workbook: multiple sheets, cell formatting, formulas and dates that know they are dates. It is what most people mean by “a spreadsheet”, and like DOCX it is really a ZIP of XML underneath.

What is a .xml file?

XML wraps data in named tags that can nest arbitrarily deep, with a schema to validate the shape. It is more verbose than JSON but remains entrenched in enterprise systems, government data feeds, and the innards of formats like DOCX and XLSX.

What to expect from this conversion

Cell values are carried across exactly as they appear. Formulas become their calculated results, and formats that hold only one table — CSV and TSV — take the first sheet of a multi-sheet workbook. Only cell values cross over, not formulas — what you see in the sheet is what you get.

Is it private?

Yes, by design. Every conversion happens inside your own browser using your device’s processor — there is no server that receives your XLSX file, so there is nothing for anyone to store, scan or leak. You can confirm it yourself: open your browser’s developer tools, watch the Network tab while you convert, and you will see no upload.

Questions about XLSX to XML

Is this Excel to XML converter free?

Yes, completely. There is no account, no daily limit, no watermark and no premium tier.

Is my XLSX file uploaded to a server?

No. The conversion runs inside your own browser using your device's processor. The file is read from your disk, converted in memory and saved back to your disk — nothing is transmitted, so there is nothing for anyone to store.

Can I convert Excel to XML online without downloading software?

Yes. This is an online Excel to XML converter that runs in your browser, so there is nothing to install and no app to trust with your files. It works the same on a phone.

What happens to the quality?

Cell values are carried across exactly as they appear. Formulas become their calculated results, and formats that hold only one table — CSV and TSV — take the first sheet of a multi-sheet workbook. Only cell values cross over, not formulas — what you see in the sheet is what you get.

Can I convert several XLSX files at once?

Yes. Select as many files as you like and they are converted one after another in a single tap, with a download for each and a zip of all of them.

Should I keep the original XLSX file?

Yes — keep it, converting never touches it. The reason to make a copy in another format is that an XLSX needs a spreadsheet program, and plenty of systems accept nothing but plain text.
