JSON to CSV
Convert JSON arrays to CSV format. Perfect for importing data into Excel, Google Sheets, or databases.
About JSON to CSV Conversion
Converting JSON arrays to CSV (Comma-Separated Values) is essential for data analysis workflows. API responses, database exports, and application logs often come in JSON format, but spreadsheet applications like Excel, Google Sheets, and LibreOffice Calc require tabular CSV data. JSON to CSV conversion flattens hierarchical data into a two-dimensional table format, making it immediately usable for data analysis, reporting, and visualization.
CSV Format Quick Reference
The CSV format, defined by RFC 4180, uses commas to separate values and newlines to separate records. The first row typically contains column headers. Values containing commas, double quotes, or newlines must be enclosed in double quotes, and literal double quotes within values are escaped by doubling them (""). While the standard specifies commas as delimiters, variations exist using semicolons (common in European locales), tabs (TSV), or pipes.
This converter automatically flattens nested JSON objects using dot notation (e.g., address.city becomes a column header). Arrays within objects are serialized as JSON strings to preserve their structure. The converter also auto-detects all unique keys across all objects in the array, ensuring every field appears as a column even if some objects are missing certain properties. This approach handles the common case of inconsistently structured JSON data from APIs.
