About Data Format Conversion
JSON, YAML, and XML are the three dominant human-readable data serialisation formats used in software development. JSON is the standard for web APIs and JavaScript applications. YAML is popular for configuration files (Kubernetes, Docker Compose, GitHub Actions) due to its clean, minimal syntax. XML remains widely used in enterprise systems, SOAP APIs, Android manifests, and document formats like DOCX and SVG.
Converting between them is a common developer task. This tool handles all six conversion directions. YAML parsing uses js-yaml, XML parsing uses the browser's native DOMParser, and all three output formats are pretty-printed for readability. All processing is client-side β your data never leaves your browser.
