Convert YAML to XML online, free. YAML is an indentation-based superset of JSON favoured for human-edited config. XML is a verbose, self-describing markup format used in SOAP, RSS and enterprise systems. YAML to XML conversion parses your YAML against the YAML 1.2.2 grammar (https://yaml.org/spec/1.2.2/), builds an in-memory model of its keys, nested objects and arrays, then re-serializes it as valid XML following the W3C XML 1.0 conventions. Processing runs in your browser in JavaScript with no upload or server round-trip — no size limit beyond your device's memory, so multi-megabyte documents convert in milliseconds and sensitive payloads never leave your machine. Typical uses include SOAP web services, RSS/Atom feeds and legacy enterprise documents.
It maps the full structure of your YAML onto well-formed XML, following the W3C XML 1.0 conventions. 100% free, no registration, and complete privacy — everything runs locally in your browser, so your data never touches a server.
Paste YAML and convert XML immediately. Conversion runs client-side, so there is no upload wait and large documents stay fast.
Nested YAML objects, tables and arrays are mapped faithfully onto XML.
Your YAML never leaves your device — everything is processed locally in JavaScript, with nothing logged or stored.
Unlimited conversions with no account, no quotas, and no watermark. Works on desktop and mobile.
A YAML document and its XML equivalent:
YAML input:
name: Alice
age: 30
email: [email protected]Output:
<user>
<name>Alice</name>
<age>30</age>
<email>[email protected]</email>
</user>Paste your YAML into the editor and press "Convert to XML". The tool parses it against the YAML 1.2.2 grammar, then re-serializes it as XML following W3C XML 1.0 conventions — instantly and entirely in your browser. You can validate or format the YAML first to be sure it is clean.
YAML anchors and aliases are expanded and comments are dropped before XML is produced, and indentation defines the structure. Note that YAML 1.1 treats words like "yes" and "no" as booleans, so quote them if you want strings.
Numbers, booleans and null are preserved as native XML types wherever XML supports them, so standard documents convert losslessly and can be read back into the same structure.
YAML (YAML Ain't Markup Language) (YAML) — YAML is an indentation-based superset of JSON favoured for human-edited config. XML (eXtensible Markup Language) (XML) — XML is a verbose, self-describing markup format used in SOAP, RSS and enterprise systems. This converter maps the structure of your YAML onto XML so you can use it for SOAP web services.
Yes. Invalid YAML is flagged with a clear error before anything is converted. Common YAML problems to check are spaces (never tabs) for indentation, consistent indent levels, and no duplicate keys. Starting from clean input keeps the generated XML accurate.
Yes. The entire YAML-to-XML conversion runs locally in your browser in JavaScript — your YAML is never uploaded, logged or stored. That matters when the data is something like Kubernetes & Docker Compose manifests, which should not leave your machine.
The generated XML is ready for SOAP web services, RSS/Atom feeds and legacy enterprise documents. Copy or download it and drop it straight into your tooling.
YAML to XML conversion transforms YAML data structures into XML (eXtensible Markup Language) format. YAML is a human-friendly configuration language with minimal syntax, while XML is a verbose, tag-based markup language used widely in enterprise systems, APIs, and configuration management. This converter takes your YAML hierarchies — maps become XML elements with child nodes, lists become repeating elements, and scalar values become element text or attributes — and wraps the entire output under a single <root> element. The conversion follows the structure of your YAML input, properly escaping special XML characters and maintaining nested relationships, all entirely in your browser. For more details, see the YAML 1.2 spec.
Convert Kubernetes manifests, Docker Compose files, or configuration YAML into XML for legacy systems that require XML input. Migrate data between YAML-based toolchains and XML-based enterprise platforms. Transform Ansible playbooks, CI/CD pipelines, or infrastructure-as-code into XML for interoperability — all without uploading your data anywhere.
XML documents must have a single root element. The converter wraps your YAML output under <root> to ensure the result is valid, well-formed XML.
A YAML list becomes repeating XML elements at the same nesting level. For example, a list named "items" becomes multiple <items></items> tags, one per list entry.
No. Conversion runs entirely in your browser — your data never leaves your device and is never logged or transmitted.
