How to Use the JSON Formatter

1. Paste or type your JSON into the input panel on the left. The tool auto-formats your JSON as soon as you paste it, so you get instant results with zero clicks. You can also click "Load sample" to try it out with example data.

2. Choose your action from the toolbar. Click Format to beautify with your preferred indentation (2 spaces, 4 spaces, or tabs). Click Minify to compress your JSON into a single line. Click Validate to check for syntax errors with precise line and column numbers.

3. Explore and export your formatted output. Switch to Tree View to navigate your JSON structure with collapsible nodes and click any node to copy its path. Use the conversion tabs to transform your JSON into CSV, XML, or YAML. Copy or download the result with one click.

All processing runs entirely in your browser using native JavaScript. Your data is never uploaded to any server, making this tool safe for sensitive or proprietary JSON data. There are no file size limits beyond your browser's memory.

Paste your JSON into the input panel, and the tool will automatically format and validate it. Then click the 'JSON to YAML' tab in the conversion section below the editor to see the YAML output. Copy or download the result with one click.
YAML (YAML Ain't Markup Language) is a human-readable data serialization format. Unlike JSON, YAML uses indentation instead of braces, supports comments, and doesn't require quotes around strings. YAML is widely used for configuration files in tools like Kubernetes, Docker Compose, and GitHub Actions.
Yes. The generated YAML is valid and can be used directly with Kubernetes, Docker Compose, Ansible, GitHub Actions, and any other tool that accepts YAML configuration files. You may need to add Kubernetes-specific fields like apiVersion and kind.
Yes. YAML is a superset of JSON, meaning every valid JSON document is also valid YAML. YAML supports strings, numbers, booleans, null, arrays (sequences), and objects (mappings), plus additional types like dates and multiline strings.
This tool focuses on JSON to YAML conversion. To convert YAML back to JSON, you would need a YAML parser. Since YAML is a superset of JSON, the conversion is straightforward but requires a dedicated YAML parsing library.
