XLSX to XML Converter
Processing entirely on your device — large files may take a moment.
Excel Spreadsheet and XML Data exist for different jobs: XLSX is the modern Microsoft Excel workbook format. It stores multiple sheets with values, styles and charts, and opens in Excel, WPS Office, Numbers and Google Sheets. XML is still required by many enterprise imports, sitemap generators and older APIs.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

Frequently asked questions
Is this XLSX to XML converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
What about special characters and non-English text?
Everything is handled as UTF-8. When you export CSV for Excel, a UTF-8 BOM is included automatically so Chinese, Japanese, Korean and accented characters display correctly on both Windows and macOS.
