CSV (Comma-Separated Values) is a ubiquitous format for tabular data, widely supported by spreadsheet programs like Microsoft Excel and Google Sheets, as well as data analysis tools. While JSON is excellent for hierarchical data, it is not ideal for direct use in these applications. A JSON-to-CSV converter is designed to bridge this gap. It typically takes a JSON array of objects, where each object represents a row. The tool extracts all the unique keys from the objects to create the header row of the CSV file. Then, it iterates through each object, mapping its values to the corresponding columns. This process flattens the structured JSON data into a simple, tabular format, making it easy to import, analyze, and visualize in a wide variety of data-processing tools.
