Convert JSON arrays to CSV spreadsheet format and CSV back to JSON. Handles nested objects with dot notation flattening.
The tool expects a JSON array of objects. Each object becomes a CSV row, and object keys become column headers.
Nested objects are flattened using dot notation. For example, {address: {city: 'NYC'}} becomes a column 'address.city'.
Yes! Switch to CSV → JSON mode to convert comma-separated data back into a JSON array of objects.
