Frequently Asked Questions

Is my data uploaded to a server?
No. The JSON to CSV conversion happens entirely locally in your browser. Your data is never uploaded to Rapidus servers.
What kind of JSON is supported?
To create a valid CSV, your JSON must be an array of objects. Each object in the array will become a row in the CSV file, and the object keys will be used as the column headers.
What happens if some objects have different keys?
The converter intelligently scans all objects in the array and collects all unique keys to ensure no data is lost. Missing values in specific rows will be left blank.
