EasyConvert / Format & Code Conversion
YAML to JSON Converter
Convert YAML to valid JSON online. Check indentation errors, preserve nested structures, and copy formatted JSON in your browser.
About YAML to JSON Converter
Convert between JSON, YAML, XML, and CSV formats. Use the browser-based interface to prepare, validate, convert, or generate the result you need.
The tool is designed to process data in the browser unless the interface explicitly states that a network request is required.
How to use this tool
- Enter, paste, or upload the source value requested by the tool.
- Choose the output format or options that match your workflow.
- Run the tool, review the result, then copy or download the output.
What this conversion does
Turn YAML configuration and data files into valid JSON.
Example input
service:
name: api
port: 8080
enabled: trueExample output
{"service":{"name":"api","port":8080},"enabled":true}Practical workflow
- Check the YAML indentation and confirm that each mapping or list is nested at the intended level.
- Select YAML to JSON, paste the document, and run the conversion.
- Inspect the formatted JSON for changed scalar types, then validate it against the receiving API or application's schema.
Common use cases
- Send a YAML configuration to an API or service that accepts JSON.
- Inspect a YAML file with JSON-aware editors, diff tools, or test fixtures.
- Normalize a small YAML document before importing it into a JavaScript workflow.
Important notes and limitations
- JSON cannot represent YAML comments, anchors, aliases, tags, or document separators, so those features may be resolved or omitted.
- Unquoted YAML values can be interpreted as numbers, booleans, dates, or null; quote values that must remain strings.
- The decoder handles one YAML document at a time. Split multi-document streams and review each result separately.
Continue your workflow
- Convert JSON back to YAML — create a readable configuration after reviewing the JSON.
- Format and inspect the generated JSON — make nested values easier to review.
- Validate the JSON structure — check the converted document against an expected schema.
