JSON zu CSV
What this tool does
Convert a JSON array of objects into a CSV spreadsheet — each object becomes one row and keys become column headers.
Supported formats
Input: .json containing an array of objects. Output: .csv.
How to use
Upload valid JSON, click Convert, and download the CSV.
Limitations & tips
The root must be an array of flat objects; nested objects and arrays are stringified or skipped. Very large JSON files may hit browser memory limits. Invalid JSON will show an error.
