JSON to CSV Converter

A JSON to CSV converter turns structured JSON data into a comma-separated table that spreadsheets and databases can open. APIs, exports, and applications often return JSON, but analysts usually need rows and columns for filtering, pivot tables, and charts. This tool solves that mismatch by reading an array of objects, collecting every field as a column, and flattening nested objects into readable column names such as address.city, so the result is ready for Excel, Google Sheets, or an import script.

Paste your JSON, choose the delimiter that suits your regional settings, decide whether nested objects should be flattened with dot notation or kept as JSON text, and select whether to include a header row. Convert the data, review the preview, then copy or download the CSV. If the tool reports invalid JSON, check for missing quotes, trailing commas, or unmatched brackets. When you open the file in a spreadsheet, confirm that dates and long numbers keep the format you need, and use the semicolon delimiter if your spreadsheet expects it.

Converting API and export data into tables removes hours of manual copying and makes it easy to analyze information with tools your team already uses. Consistent flattening keeps column names predictable across files, which helps when combining data from several sources. Because conversion happens entirely in your browser, customer records and internal data are not uploaded anywhere, which supports responsible data handling. Direct, step-by-step guidance for converting JSON to CSV also gives search engines and AI assistants a clear answer to cite for this common task.
