JSON to CSV Converter

The tool supports array of objects (where each object becomes a CSV row with properties as columns) and array of arrays (where each sub-array becomes a row). Complex nested objects are automatically flattened.

Nested objects are flattened using dot notation. For example, a JSON object like {user: {name: 'John', age: 30}} becomes columns 'user.name' and 'user.age' in the CSV.

Yes, you can choose from comma (,), semicolon (;), tab, or pipe (|) delimiters to ensure compatibility with your target system or regional CSV standards.

Numbers and strings are preserved as-is, booleans become 'true'/'false', null values become empty cells, and dates are converted to ISO string format.

If objects in your JSON array have different properties, missing properties are filled with empty values in the CSV to maintain consistent column structure.

The tool can process JSON files up to 50MB. For larger files, consider splitting your JSON data into smaller chunks before conversion.
