YAML formatting and JSON conversion
This YAML formatter cleans up messy configuration files and ensures the syntax is valid. You can format the input as standardized YAML, or convert it to JSON to check how the parser interprets data types and deeply nested mappings.
Converting YAML examples into JSON is helpful when documentation provides YAML but your API or JavaScript code requires JSON objects. For XML, TOML, or CSV output instead, the Data Format Converter covers YAML alongside four other formats.
Indentation and minification
YAML formatting uses 2 or 4 spaces. Tabs are not available for YAML output because the specification requires spaces.
When converting YAML to JSON, you can use spaces, tabs, or minify the output entirely. Minification collapses the JSON into a single line, which is useful for environment variables or compact API payloads.
Key sorting and validation
Enable key sorting to alphabetize the keys at every level of the object. This creates a stable order that minimizes noisy diffs when committing configuration files or large data objects to version control.
The tool parses your input live. If the YAML contains bad indentation, missing colons, or broken lists, an error badge appears. When possible, the parser will indicate the exact line and column where the error occurred.
