Format Converter
Two-way conversion between JSON, YAML and XML. Note: JSON→XML output is wrapped under a <root> node; XML attributes/text nodes appear as @_xxx / #text; comments are lost when the target is JSON.
FAQ
How do JSON, YAML and XML differ?
JSON is a lightweight data exchange format, YAML is more human-readable and common in config files, and XML fits markup scenarios. This tool converts between all three locally in your browser.
Does converting JSON to XML lose information?
JSON has no concept of attributes or comments, so XML output is wrapped under a single root node. XML attributes and text nodes appear as @_xxx and #text; comments are lost when converting to JSON.
Does converting upload my data?
No. All conversions run locally in your browser — data is never uploaded.
