JSON Formatter
Format minified JSON with readable indentation.
Open toolConvert common YAML and JSON structures both ways. Your input stays in this browser during processing.
Your text and settings stays in this browser.
Convert straightforward YAML key-value mappings into JSON, or JSON objects and arrays into readable YAML, in either direction.
JSON from simple YAML key-value mappings, or readable YAML from JSON objects and arrays.
Convert a small environment-style YAML mapping into JSON for an application setting.
Inspect values that look like dates, booleans, numbers or null after conversion, because YAML and JSON do not represent every feature in the same way. Comments and anchors may not survive a round trip. Start with a short representative sample and compare value types as well as displayed text. Keep the original configuration, and use the destination application's validator before deploying the converted version.
Simplify it to basic key: value lines or use a full YAML parser for advanced YAML syntax.
The text and settings is processed on this device and is not uploaded to MyFileNest. Closing or refreshing the page clears the active session.
Practical limit: Large text or structured-data inputs can respond more slowly in the browser. Verify generated output before using it in a production workflow.
