JSON / YAML / TOML Converter
Convert between JSON, YAML, and TOML data formats. Paste your data, pick a target format, and convert instantly.
Why Convert Between Formats?
JSON, YAML, and TOML each suit different contexts. JSON is standard for APIs and package manifests, YAML is the go-to for Kubernetes and CI/CD configs, and TOML is favored by Rust's Cargo and Python's pyproject. Converting between them saves manual rewriting.
How This Converter Works
Paste or type your data in any of the three formats. The tool auto-detects the input format, then converts to your chosen target with proper indentation and structure preserved.
Validate and Pretty-Print
Beyond conversion, the tool also validates your input and pretty-prints the output. This makes it useful for quickly tidying up minified JSON or catching syntax errors in hand-edited YAML files.
