One converter for 8 data formats: JSON, XML, YAML, CSV, TSV, INI, TOML and Properties. Convert any format to any other, and the tool auto-detects your input. It validates syntax and shows clear errors, converts as you type, and lets you pretty-print or minify. Options include CSV/TSV headers, auto-typing numbers and booleans, XML escaping and removing nulls. Upload a file, swap formats in one click, and copy or download. Everything runs in your browser. No signup.
