Frequently Asked Questions

What format should my JSON be in?

Your JSON should be an array of objects where each object represents a row. For example: [{"name":"John","age":30},{"name":"Jane","age":25}]. Nested objects are flattened into columns.

Can I convert nested JSON to CSV?

Yes. Nested objects and arrays are automatically flattened. Nested keys are joined with dots (e.g., 'address.city' becomes a column name) to create a flat CSV structure.

What delimiter does the CSV use?

The converter uses commas as delimiters by default. If your data contains commas, values are properly quoted to prevent formatting issues.

Can I use this with API data?

Yes. If your API returns JSON array data, simply copy the response and paste it into the converter. This is commonly used to export API results to spreadsheets for analysis.

Does this tool handle nested JSON objects?

Our JSON to CSV converter flattens nested objects using dot notation (e.g., user.name). Arrays within objects are converted to comma-separated strings. Each top-level object becomes a CSV row.
