← All Tools
🔄 JSON to YAML Converter
Convert JSON objects and arrays into readable YAML.
Why it is useful
It helps developers move structured data into configs, documentation examples, and tools that expect YAML.
How it works
The browser parses JSON and serializes equivalent data with YAML-style indentation.
Best input
Paste valid JSON with the structure you want to convert.
Config tip
Review strings, booleans, nulls, and indentation before using output in production configs.
Privacy note
Conversion happens locally in your browser.
Important limitation
YAML has features and parser differences that JSON does not, so verify output with your target tool.
Quick answers
Is every JSON file valid YAML?
JSON is generally compatible with YAML, but generated style and parser expectations can vary.
Can it preserve comments?
JSON has no comments, so there are none to preserve.
Common Use Cases
Convert API JSON into a config draft
Paste a JSON response or manifest and turn it into readable YAML before adapting it for a deployment file.
Prepare docs examples for YAML-first tools
Convert a JSON sample into YAML syntax when writing README examples for Kubernetes, CI, or static-site config.
Review generated settings before commit
Use the side-by-side output to spot booleans, null values, arrays, and indentation that need checking in your target parser.
