JSON to CSV Converter

Converts an uploaded JSON file (containing an array of flat objects) into CSV format.

Instructions

Upload your JSON file. The tool expects a JSON array where each element is a flat object (key-value pairs). It will use the keys from the *first* object in the array as the CSV header row. The data will then be converted into a CSV file, ready for download.

File should contain a JSON array of objects, like: [{"colA": 1, "colB": "x"}, {"colA": 2, "colB": "y"}]
