Frequently Asked Questions
What JSON structure works best for CSV conversion?
A JSON array of flat objects works best — each object becomes a row and each key becomes a column. For example: [{"name":"Alice","age":30},{"name":"Bob","age":25}].
Does it support nested JSON objects?
Nested objects are flattened or serialized as strings in the CSV output. For complex nested data, consider flattening your JSON first using a transformation step.
Can I open the output in Excel?
Yes. Download the .csv file and open it directly in Microsoft Excel, Google Sheets, or any spreadsheet application that supports CSV.
Is there a size limit?
There's no hard limit — but very large JSON datasets may slow down browser rendering. For best performance, process in batches if needed.
