About JSON to CSV Conversion
JSON data from REST APIs, database exports, and application logs often needs to be analyzed in a spreadsheet. Converting JSON to CSV lets you open your data in Microsoft Excel, Google Sheets, or LibreOffice Calc for filtering, sorting, creating pivot tables, and generating charts — tools that data analysts and business users are most comfortable with.
FileForge handles JSON arrays of objects — the most common structure from REST APIs and database dumps. The keys of the first object become the CSV column headers; each object in the array becomes a row. Values containing commas, quotes, or newlines are properly escaped per the CSV standard. The output is a UTF-8 encoded CSV compatible with all major spreadsheet applications.
