What is the YAML / JSON / XML Converter?
This tool converts between the three most common data-serialization formats — JSON, YAML and XML. Paste data in one format, pick the target format and get the converted output instantly.
How to use it
Select the input format, select the output format, paste your data in the input panel and click Convert. The converted result appears in the output panel ready to copy or download.
JSON vs YAML vs XML
JSON is compact and ubiquitous in web APIs. YAML is human-friendly and common in configuration files (Docker Compose, Kubernetes, CI pipelines). XML is verbose but supports attributes and namespaces, making it the standard in enterprise systems, SOAP services and document formats.
Is my data safe?
Absolutely. Every conversion runs entirely in your browser — nothing is uploaded to a server. You can verify by disconnecting from the internet and using the tool offline.
