Frequently Asked Questions
What JSON format does the converter accept?
The converter expects a JSON array of objects, where each object represents a row. For example: [{"name":"Alice","age":30},{"name":"Bob","age":25}].
How are nested objects handled?
Nested objects are flattened using dot notation. For example, {"address":{"city":"NYC"}} becomes a column named "address.city" with value "NYC".
Can I use this for Excel?
Yes. CSV files can be opened directly in Excel, Google Sheets, or any spreadsheet application. Use comma or semicolon delimiters depending on your locale settings.
Is there a size limit?
The conversion runs entirely in your browser, so there is no server-imposed limit. Very large files are limited only by your device's available memory.
