How it works
How to use the CSV to XML
Paste or open CSV
Paste your CSV, drop a file onto the editor, or load the sample.
Adjust the options
Attributes become keys prefixed with "@" and element text becomes "#text"; repeated elements become arrays.
Copy or download the XML
The output updates as you type. Invalid input is highlighted with the exact line and column.
About CSV and XML
CSV (comma-separated values) is the lingua franca of spreadsheets and data exports: one record per line, fields separated by commas, quoted when needed (RFC 4180).
XML (Extensible Markup Language) represents data as nested elements with attributes. It is still everywhere in enterprise systems, SOAP services, RSS feeds, Office documents and Android resources.
How the conversion works
Attributes become keys prefixed with "@" and element text becomes "#text"; repeated elements become arrays. Conversion happens entirely in your browser, so even sensitive data never leaves your device.

FAQ
Frequently asked questions
Is CSV to XML conversion lossless?
The data is preserved. Formatting details that XML cannot represent (such as comments or attribute-versus-element choices) may change.
Can I convert XML back to CSV?
Yes — press Swap to reverse the direction, or open the XML to CSV converter.
Is my data uploaded anywhere?
No. Everything runs locally in your browser — nothing you paste or open is sent to a server, logged or stored. The tool keeps working offline once the page has loaded.
