YAML to JSON Converter
Paste any YAML file or block and get a clean, formatted JSON object in return. The parser handles nested maps, lists, quoted strings, numbers and booleans, and preserves your structure so it is ready to paste into code, tools or APIs.
Quick Answers
- What YAML does this converter support?
- It handles the common subset: nested block maps, block sequences, inline scalar values, quoted strings, numbers, booleans and null. Anchors, aliases and multi-line literal blocks are not expanded.
- Is YAML to JSON conversion lossless?
- For standard maps and lists yes. As with any YAML parser, anchors/aliases are resolved as their dereferenced value and comments are discarded.
- Can I convert JSON back to YAML here too?
- Yes. Use the companion JSON to YAML converter on this site to go the other direction.
How to use YAML to JSON Converter
