Free Data Converters
Convert between structured data formats — CSV, JSON, XML, YAML, TSV, and more. Schema is inferred where possible; nested JSON flattens to dot-notation CSV columns and vice versa. Common uses: import a CSV export into a JSON-fed tool, convert YAML config to JSON for an API that requires it, normalize XML records into a spreadsheet-friendly CSV.
