YAML to XML

Convert YAML to XML free, in seconds. Paste your data below, press Convert, then copy the result and use it with APIs, feeds and legacy systems. Everything runs in your browser, so nothing is ever uploaded.

YAML input

Paste your YAML below, then press Convert.

Lists of maps convert best. Nested maps are flattened with dot notation.

XML output

Waiting for YAML input.

Private by design: parsing uses the js-yaml library (loaded once from a CDN); the conversion itself happens locally and your data is never uploaded.

How this conversion works

Paste YAML into the input box and press Convert (or just keep typing, conversion happens as you type). The tool parses it with the js-yaml library, then serializes it to XML with an XML declaration, escaping special characters and sanitizing element names. Parsing uses the js-yaml library (loaded once from a CDN); the conversion itself happens locally and your data is never uploaded.

About the XML output

Each record becomes a <row> element containing one child element per field, and nested objects become nested elements, so the structure mirrors your data. Characters like &, < and > are escaped automatically, and field names are sanitized into valid XML element names. The output starts with an XML declaration, so parsers accept it as-is.

YAML to XML FAQs

Why convert YAML to XML?
XML still powers RSS feeds, sitemaps, SOAP services, Android layouts, Maven configs and plenty of enterprise APIs. Converting to XML is useful whenever a system you integrate with only speaks XML and your data starts life in a friendlier format.
How is my YAML parsed?
With the js-yaml library. A list of maps becomes one row per item, a single map becomes one row, and nested maps are flattened with dot notation so tabular output stays clean.
How is my data mapped to XML elements?
Each record becomes a <row> element with one child element per field. Nested objects become nested elements, and the document starts with an XML declaration so parsers accept it without tweaks.
What about special characters and unusual field names?
Characters like & < > " and ' are escaped automatically, and field names are sanitized into valid XML element names (spaces and symbols become underscores), so the output always parses.
Is my data sent to a server?
No. parsing uses the js-yaml library (loaded once from a CDN); the conversion itself happens locally and your data is never uploaded.
