About JSON to CSV Conversion
JSON (JavaScript Object Notation) and CSV (Comma-Separated Values) are two of the most common data interchange formats. JSON is popular in APIs and web applications, while CSV is the standard for spreadsheets, databases, and data analysis tools like Excel and Google Sheets.
How This Converter Works
Paste a JSON array of objects and the tool extracts all unique keys as CSV column headers, then maps each object to a row. Values containing commas, quotes, or newlines are properly escaped. The reverse mode parses CSV with a header row and produces a JSON array.
Common Use Cases
Exporting API response data to a spreadsheet, converting CSV exports to JSON for importing into a database, or transforming data between services that expect different formats.
