Frequently Asked Questions
How does JSON to CSV conversion handle nested objects?
Nested objects are flattened using dot notation. For example, {address: {city: 'NYC'}} becomes a column named 'address.city' with value 'NYC'.
What JSON structure works best for CSV?
An array of objects with consistent keys works best, where each object becomes a row and each key becomes a column header.
Can I use custom delimiters?
Yes, you can choose between comma, tab, semicolon, or pipe as the field delimiter for your CSV output.
