Use JSON to CSV when you need to import API data into spreadsheet applications like Excel or Google Sheets for analysis. It is ideal for converting database query results, analytics data, or configuration exports into a tabular format. Data analysts and developers commonly use it to transform structured JSON payloads into shareable, human-readable spreadsheet files.
Arrays of objects work best, where each object becomes a CSV row and object keys become column headers. Single objects and nested arrays are also handled. The tool automatically detects the structure and maps JSON properties to appropriate CSV columns.
Yes, nested objects are automatically flattened using dot notation (e.g., address.city). This preserves the hierarchical relationship in a flat CSV structure. Arrays within objects are serialized as comma-separated values within a single cell.
