Flatten JSON to CSV Easily

Convert complex nested JSON arrays into flat CSV files. Easily export API responses into Excel or Google Sheets.

While JSON is the absolute standard for machine-to-machine communication, business teams and analysts run their worlds on spreadsheets. When a developer gets a request to "export the user database," converting JSON to CSV is required. Our JSON to CSV converter intelligently parses arrays of JSON objects. It extracts all the unique keys across every object to create the CSV Header row. It then maps the values to their corresponding columns.

If it encounters nested objects (like `"address": {"city": "NY"}`), it intelligently flattens them using dot notation (generating a column named `address.city`). This ensures no data is lost during the conversion from a 3D tree to a 2D spreadsheet grid.

Frequently Asked Questions

What happens if a JSON object is missing a key?
The converter creates the column universally based on all objects. If a specific object lacks that key, the resulting CSV row will simply have an empty comma-separated cell for that column.
