JSON to YAML

How to use JSON to YAML

1. Paste valid source-format data into JSON to YAML.
2. Confirm the source structure matches the expected input format.
3. Run JSON to YAML to generate the target format.
4. Inspect nested values and escaping before copying the converted result.

Common uses

• A platform engineer can convert an application settings object into a readable YAML starting point.
• A documentation writer can show the same API example in JSON and YAML without retyping nested values.

Example input

{"name":"Ada","tags":["web","data"]}

Example result

service: catalog
replicas: 2
ports:
  - 8080
  - 8081

Common mistakes

• Duplicate keys in the JSON source. Fix: resolve the conflict before conversion.
• Expecting comments to survive. Fix: add documentation comments after conversion because standard JSON contains none.
• Assuming YAML scalars will always be interpreted identically by every downstream parser. Fix: quote values whose type must remain a string.

Tips for reliable results

• Check one representative nested record before converting a large input.
• Review arrays, attributes, null values, dates, and leading zeros because formats represent these values differently.
• Validate the generated output with a target-format validator before importing it into another system.
