XLSX vs XML: Format Comparison
Key differences between the two formats
| Feature | XLSX | XML |
|---|---|---|
| Format type | Binary spreadsheet (ZIP of XML) | Plain text markup with tags |
| Readability | Requires spreadsheet app | Human-readable, verbose |
| Enterprise use | Finance and business data | Enterprise data exchange and SOAP |
| Schema support | No built-in schema | XSD and DTD for strict validation |
| Tooling | Excel, LibreOffice, Google Sheets | XPath, XSLT, SAX/DOM parsers |
| Nested data | Flat rows only | Arbitrarily nested elements |
| File size | Compact binary | Verbose — larger than equivalent JSON |
When to Convert
Common scenarios where this conversion is useful
Generate data feeds from spreadsheets

Frequently Asked Questions
Each spreadsheet row becomes an XML element. Column headers become child element names and cell values become their text content. All rows are wrapped in a root element.
The root element is automatically named based on the data structure. If you need a specific element name, rename the sheet tab in Excel before converting — the sheet name is used as context.
Cell values are serialized as XML text content. XML itself does not enforce types in elements without a schema. Consumers typically parse the text as numbers on their end.
The first (leftmost) sheet in the workbook is converted. Rearrange the sheets if you need a different one to be first.
The converter produces well-formed XML but does not generate an XSD schema. You can write an XSD based on your column names and validate using xmllint or online tools.
Empty cells are omitted from each row element. Only cells with values generate child elements.
The output is formatted with indentation for readability. If you need compact XML for a specific system, you can minify it with an online XML minifier.
