AkousaJSON to CSV Converter
Convert JSON arrays to CSV format with delimiter selection, nested object flattening, and header options.
About JSON to CSV Converter
The JSON to CSV Converter transforms JSON arrays of objects into comma-separated values (CSV) format, automatically extracting all unique keys as column headers and flattening nested objects into dot-notation column names. JSON is the universal data interchange format for APIs and web services, while CSV is the most widely supported format for spreadsheets (Excel, Google Sheets) and data analysis tools (Pandas, R, Tableau). This browser-based tool handles nested structures, mixed-type arrays, and special characters with proper CSV quoting and escaping.
How to Use
Paste a JSON array of objects into the input area, or click Load Sample to see a working example. Configure options: toggle header row inclusion, enable nested object flattening (converts nested objects into dot-notation columns), and select the delimiter (comma, tab, semicolon, or pipe). Click Convert to CSV and copy the result to clipboard or download it as a .csv file.
