About this tool
Convert XML into YAML in a single step. XML is the markup format behind SOAP, RSS, sitemaps and countless enterprise feeds; YAML is the configuration format used by Kubernetes, CI pipelines and Docker Compose. The converter is structure-aware rather than a text substitution, so nesting, types and ordering are preserved.
When you would use it
- Turning XML output into a config file a pipeline can read
- Migrating a dataset from XML to YAML
- Inspecting XML in a shape that is easier to read

Questions
Frequently asked
Is XML to YAML conversion lossless?
Structure and text content are preserved. Attribute-versus-element distinction is kept via the
@ prefix, so the conversion can be reversed.Why convert XML to YAML?
XML is the markup format behind SOAP, RSS, sitemaps and countless enterprise feeds, while YAML is the configuration format used by Kubernetes, CI pipelines and Docker Compose. Converting is usually about handing data to a tool that only speaks one of them — a Kubernetes manifest or CI pipeline, for instance.
Is my data uploaded anywhere?
No. Every tool on JSONWorks runs entirely in your browser using JavaScript. Your input is never sent to a server, never logged and never stored. The simplest proof is to disconnect from the internet — the tools keep working. The site does load Google Fonts and a Google Analytics page-view tag, so you will see those two requests in your network tab, but neither receives anything you type or paste.
