Convert JSON arrays to CSV format and CSV to JSON. Handles nested objects and auto-detects types.
JSON-CSV conversion transforms data between JavaScript Object Notation (structured key-value pairs) and Comma-Separated Values (tabular rows). It's commonly used for data migration, spreadsheet imports/exports, and API integrations.
JSON to CSV: Converts an array of JSON objects into CSV format. Each object becomes a row, and object keys become column headers.
CSV to JSON: Parses CSV data where the first row contains column headers. Each subsequent row becomes a JSON object.
Nested objects are flattened using dot notation. Numbers and booleans are automatically detected and converted to proper types.
