Frequently Asked Questions
Does the converter handle nested JSON objects?▾
Nested objects are flattened using dot notation for column headers. For example, a field "address.city" becomes a single CSV column.
What happens if JSON objects have different keys?▾
The converter creates columns for all unique keys found across all objects. Missing values are left as empty cells in the CSV output.
Is there a size limit for JSON to CSV conversion?▾
The tool runs entirely in your browser, so it can handle files up to several megabytes without uploading anything to a server.
