Data Formats Tools
Move data between formats. Convert JSON to CSV, XML or YAML and back, read TOML configuration as JSON, generate TypeScript interfaces from sample JSON, convert HTML to JSX, build Markdown tables and create clearly fictional mock data for testing. Converters show parse errors with line numbers and explain how nested data, attributes and arrays are mapped, so you can predict the output for your own files.
