Guide
How to use this tool
- 1
Paste JSON or YAML
Enter valid data in the source format you want to convert.
- 2
Choose the output format
Convert JSON to YAML or YAML to JSON depending on what you need.
- 3
Validate the result
Check nesting, lists, and value types before saving or reusing the converted data.
Tips and best practices
- YAML relies heavily on indentation, so check spacing and nesting first when a YAML input fails to parse.
- After conversion, review strings that the target format might interpret as numbers, booleans, or null values.
Frequently asked questions
Can JSON and YAML represent the same data?
They share many common structures such as objects, lists, and scalar values, although their syntax and some interpretation rules differ.
Why is indentation important in YAML?
Indentation directly defines YAML document structure. A misaligned level can therefore change the meaning of the data or make the document invalid.
Are my JSON or YAML data uploaded to a server?
No. Conversion runs locally in your browser.
