JSONからCSV について

JSON to CSV Converter takes a JSON array of objects and transforms it into comma-separated value (CSV) format. Property names from the first object are used as column headers, and all objects are written as rows.

Fields containing commas, newlines, or double quotes are properly escaped according to CSV standards. The output is ready to import into Excel, Google Sheets, or any data tool.
