Pro Tips
- •The first row of the sheet is used as XML element names for each column - keep headers short and free of special characters
- •Header names are automatically sanitized into valid XML element names (spaces and symbols become underscores)
- •Special characters like <, >, and & in cell values are automatically escaped to keep the XML valid
- •If your workbook has multiple sheets, switch between them with the Sheet selector - each one converts independently
- •The whole file is read and converted locally in your browser - nothing is uploaded anywhere

When to Use This Tool
Convert spreadsheet data into XML for import into older enterprise systems or SOAP-based APIs that require XML input.
Exchange spreadsheet data with partners or systems that standardize on XML rather than JSON or CSV.
Maintain configuration data in a spreadsheet for non-technical editors, then export it as XML for applications that read XML config.
Produce XML input for XSLT transformations or document-generation pipelines from spreadsheet source data.

Frequently Asked Questions
Can I convert a workbook with multiple sheets?
Yes. After uploading, use the Sheet selector to choose which sheet to convert. Each sheet is converted independently into its own XML document.
What happens if my column headers aren't valid XML names?
Header names are automatically sanitized - spaces and special characters are replaced with underscores, and a name is prefixed with an underscore if it doesn't start with a letter.
How is the XML structured?
The output has a <rows> root element containing one <row> element per data row, with each column becoming a child element named after that column's header.
Is my spreadsheet uploaded to a server?
No. The entire file is read and converted locally in your browser using the SheetJS library. Your data never leaves your device.
What happens to formulas in my spreadsheet?
Formulas are converted using their last calculated value, not the formula text itself, since XML has no concept of spreadsheet formulas.
