Frequently Asked Questions

What kind of JSON structure does this tool support?

This tool is designed to convert a JSON array of objects (e.g., `[{'key': 'value'}, {'key': 'value'}]`). Each object's keys will become the CSV headers.

Does it handle nested JSON objects or arrays?

Currently, it handles flat key-value pairs within each object. For deeply nested JSON, it will treat nested objects as string values. Complex nested arrays are not fully supported for flattening into a single CSV row.

Is my JSON data secure?

Yes, all JSON to CSV conversion happens directly in your browser. Your data is not sent to our servers, ensuring complete privacy and security.
