Frequently Asked Questions
What JSON format does this converter expect?
It expects a JSON array of flat objects, e.g., [{"name": "Alice", "age": 30}]. Each object becomes a row, and all unique keys become CSV column headers.
How does the converter handle nested JSON objects?
Nested objects and arrays are serialized as JSON strings within the CSV cell. For deeply nested data, consider flattening your JSON first for a cleaner CSV output.
Are special characters like commas and quotes handled correctly?
Yes. Fields containing commas, double quotes, or newlines are automatically wrapped in quotes and escaped according to the RFC 4180 CSV standard.
Can I open the downloaded CSV in Excel or Google Sheets?
Yes. The output is a standard CSV file that opens correctly in Microsoft Excel, Google Sheets, LibreOffice Calc, and any other spreadsheet application.
