Data Format Encoder & Decoder

Convert between JSON, CSV, YAML, and TOML with auto-detection

How to Use Data Format Converter:

  • Paste your data (JSON, YAML, TOML, or CSV) into the "Input Text" box.
  • The tool will attempt to automatically detect the input format.
  • Select the desired "Convert to" format from the dropdown.
  • Click "Convert". The converted data will appear in the "Output" box.

Notes:

  • Auto-detection prioritizes JSON > YAML > TOML > CSV. Ensure your input is well-formed.
  • CSV detection requires a header row and consistent delimiters (comma, semicolon, tab, or pipe).
  • Conversion from complex nested structures to CSV may involve flattening or schema inference, which might simplify the data.
  • TOML output requires the root element to be a table (dictionary); lists will be wrapped (e.g., `data = [...]`).
