About the JSON ↔ YAML
JSON ↔ YAML converts data between the two most common configuration formats in both directions. Paste JSON to get readable YAML for your config files, or paste YAML to get strict JSON for an API or program. The conversion is handled in your browser, so your configuration data stays local.
How to use
- Paste your JSON or YAML into the input area.
- Select the direction you want to convert.
- Review the converted output for correctness.
- Copy the result into your config file or application.
Frequently asked questions
- Why convert between JSON and YAML?
- YAML is easier for humans to read and write in config files, while JSON is widely used by APIs and programs, so converting lets you move between the two.
- Does the conversion preserve nested structures?
- Yes. Nested objects and arrays are mapped between the equivalent JSON and YAML structures.
- Is my configuration data uploaded?
- No. The conversion runs entirely in your browser, so nothing you paste is sent to a server.
