Format, minify, validate, and convert JSON and YAML
Paste your JSON or YAML in the input area. You can type it, paste from clipboard, or upload a file.
Choose a mode: Format (pretty-print), Minify (compact), JSON to YAML, or YAML to JSON.
Select indentation (2 or 4 spaces) for formatted output. This only applies when formatting or converting to readable output.
View the result in Raw (text) or Tree (expandable nodes) tab. Use path view to see the path to each value.
Copy the result to clipboard or download as a .json or .yaml file for use in your project.
Optionally paste a JSON Schema and click Validate to check if your JSON conforms to the schema.
Fix any syntax errors shown by the tool. Common issues include missing commas, trailing commas, or unquoted keys.
Use the sample dropdown to load example JSON (user, product, or API response) and try the tool with sample data.
JSON (JavaScript Object Notation) is a lightweight data format used to store and exchange data between systems. It is human-readable and supported by most programming languages.
Valid JSON must have proper syntax: keys in double quotes, correct comma placement, and balanced brackets. The tool will highlight errors and show where they occur.
Minified JSON removes all unnecessary whitespace and newlines to reduce file size. It is commonly used in production for APIs and config files.
YAML is a human-friendly format that converts to JSON. Use the tool to convert between JSON and YAML for config files or data exchange.
Paste your JSON in the input area, choose a mode (format, minify, or convert), and view the result. All processing runs in your browser; nothing is sent to servers.
Yes. The tool runs entirely in your browser. Your data is never uploaded or stored on any server.
Use the tree view to expand and collapse nodes, or the path view to see the path to each value. Copy or download the result for use elsewhere.
Paste a JSON Schema in the schema section and click Validate to check if your JSON conforms to the schema. Invalid paths will be highlighted.
Yes. Use the upload button or paste from clipboard. The tool accepts both JSON and YAML input when converting between formats.
Yes. Format and validate JSON in the tool, then use the copy or download button to use it in your code or API requests.
