About The YAML to JSON Converter

This tool allows you to seamlessly convert YAML (YAML Ain't Markup Language) data into the universally recognized JSON (JavaScript Object Notation) format. While YAML is praised for its human-readability, JSON is the de facto standard for web APIs and data interchange between systems. Our converter helps you bridge this gap by accurately translating your YAML files into valid JSON.

Key Features:

  • Accurate Parsing: Reliably parses complex YAML, including anchors, aliases, and multi-document streams.
  • Built-in YAML Validation: Instantly validates your input YAML and provides clear, descriptive error messages if the syntax is incorrect.
  • Flexible JSON Output: Choose between a "prettified" (indented and readable) JSON or a minified (single-line) JSON. You can also control the indentation level (2/4 spaces or tabs).
  • File & Sample Inputs: Directly upload `.yaml`/`.yml` files or load a sample to get started quickly.
  • Completely Secure: Your data's privacy is guaranteed. All conversions are processed directly within your browser, with nothing sent to any server.

How to Use:

  1. Paste your YAML code into the "Input YAML" text area, or click "Load File" to upload from your device.
  2. Use the "Sample" button to load a demonstration YAML.
  3. Adjust the "Prettify JSON", indentation, and "Convert all documents" options as needed.
  4. Click the "Convert to JSON" button.
  5. The valid JSON output will appear in the right-hand panel instantly.
  6. If there's an error in your YAML, a helpful message will guide you to the problem.
  7. Use the "Copy", "Download", or "Clear" buttons to manage the result.
