XML to YAML Converter - Convert XML to YAML Online

XML → YAML

About the XML → YAML playground

XML → YAML converts hierarchical XML markup into clean, indentation-based YAML. Elements become mapping keys, nested elements become nested mappings, repeated sibling elements become sequences, and attributes are preserved (commonly under a dedicated key). The result is far easier to read and edit than the original tag soup, which is handy when migrating legacy XML config to YAML-based tooling.

XML (eXtensible Markup Language) is a verbose, tag-based markup language used for documents and data interchange. YAML (YAML Ain't Markup Language) is a concise, human-readable serialization format that relies on indentation instead of closing tags. This converter walks the XML tree and re-expresses each node as YAML mappings and sequences, trimming the syntactic noise while keeping the data hierarchy intact.

How it works

Write

The main file is the entry point for each run.

Give it input

Use the Input panel to pipe standard input to your program when it needs data.

Run

Run sends your code to a fresh hosted runtime and streams the result into the output panel.
