JSON / YAML Converter

JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write. YAML (YAML Ain't Markup Language) is a human-readable data serialization standard that uses indentation for structure. Both are commonly used for configuration files and data exchange.

JSON is widely used in web APIs and JavaScript applications due to native browser support. YAML is preferred for configuration files, CI/CD pipelines, and documentation due to its more human-readable syntax with comments and multi-line strings support.

Most data converts cleanly between JSON and YAML. However, some YAML-specific features like comments and multi-line strings are not preserved when converting to JSON, as JSON doesn't support these features.

The converter validates the input and displays clear error messages if the syntax is invalid. Fix the errors before converting to ensure accurate results.

This tool runs entirely in your browser, so very large files may impact performance. For best results, use files under a few megabytes in size.
