Online YAML Parser is a free YAML Tools utility that runs entirely in your browser — nothing you enter is uploaded.
Converts one document using JSON-compatible values and string mapping keys. Numbers that would change during conversion, negative zero, nonfinite values, timestamps, binary data, sets, ordered maps, pairs, merge keys, cycles and unknown tags are rejected. Quote values only when text is intended; this changes their type. Ordinary aliases are expanded for JSON. Comments, quote style and numeric spelling are not retained. Limits: 2 MiB of text, 50,000 expanded values and 100 nesting levels.
How to use Online YAML Parser
- Paste one YAML document to produce a JSON preview.
- Review strings, numbers, arrays and object keys in the completed output.
- Resolve unsupported values or syntax errors. This browser preview is not a test of a Java, Go or PHP runtime.
- Copy the current completed JSON and check it against the receiving application’s requirements.
About this tool
This browser tool works with the supported JSON-compatible subset of YAML described above. A completed result means that this conversion succeeded; it does not validate an application schema, a deployment configuration or another programming language’s parser.
Keep the original source before formatting or conversion. Formatting normalizes presentation and removes comments. The operation runs locally in this browser and does not upload the entered document to a conversion service.
