1Introduction
JSON to CSV is a practical online data conversion tool that quickly organizes JSON arrays or objects into CSV table format. When handling API responses, config files, or log data that need to be imported into Excel or databases, CSV is the universal table format, and this tool solves exactly that conversion need. It automatically flattens nested JSON objects so even complex structures become regular two-dimensional tables. A customizable delimiter lets you choose commas, semicolons, or tabs to match CSV conventions across countries and software. The whole process runs in the browser without file upload, keeping data safe. For operations staff, test engineers, and data analysts who work with data often, this tool cuts manual data-organizing time and avoids errors from format conversion. It helps with reports, data migration, and quick preprocessing.

3FAQ
Does JSON to CSV support nested objects?
Yes, nested objects are flattened, with field names joined by dots, e.g., "address.city".
What if the CSV is garbled after conversion?
Please ensure the CSV file is saved with UTF-8 encoding, or use our export function which automatically handles encoding.
