JSON to YAML

What is JSON to YAML?

JSON is a subset of YAML 1.2, so any valid JSON can be expressed as YAML. The converter parses your JSON and writes block-style YAML, which is easier to read and edit in configuration files.

How to use JSON to YAML

1. Paste your input into the editor above, or select Sample to load an example.
2. Select Convert to YAML. If the input cannot be processed, a message explains what to fix.
3. Use Copy or Download to take the result with you, and Clear to start again.

Example

Input

{"service":"api","ports":[80,443]}

Output

service: api
ports:
  - 80
  - 443

Practical use cases

• Create configuration files
• Move data between formats
• Improve configuration readability

Common problems

• Starting with invalid JSON
• Assuming comments can survive conversion
• Ignoring YAML indentation after editing
