Convert your JSON file to CSV format instantly — perfect for Excel import
or click to browse · Max 20MB
JSON to CSV conversion transforms a structured JSON array of objects into a tabular CSV file that opens in Excel, Google Sheets, Numbers, or any spreadsheet application. JSON is the standard format used by REST APIs, web applications, MongoDB, and modern databases — but CSV is the universal language of business reporting, data analysis, BI tools, and database imports. Converting JSON to CSV makes API responses instantly usable for accountants, analysts, marketers, and anyone who works in spreadsheets. The converter automatically detects all unique keys across the JSON objects and uses them as column headers, so no data is lost even when the objects have inconsistent structures.
Common use cases: exporting REST API responses into Excel for business analysis; converting MongoDB collections for spreadsheet review; preparing JSON data for BI tools like Power BI or Tableau; transforming web scraping results into Excel-friendly format; sharing API data with non-developer team members; importing JSON exports into legacy ERP or accounting systems that require CSV; preparing data for mail merge campaigns; converting Postman or Insomnia API responses; and turning structured logs into spreadsheet rows for analysis and pivoting.
Input JSON:[Output CSV:

Upload your JSON file (must be an array of objects), click Convert to CSV, and download the resulting CSV file. Object keys are automatically used as column headers, and each object becomes one row in the spreadsheet.
The input must be a JSON array of flat objects. Nested objects and arrays are converted to JSON strings within their cells. For best results, flatten nested structures before conversion.
CSV is the universal format for spreadsheets — Excel, Google Sheets, Numbers — and the standard for data analysis tools, BI dashboards, and database imports. Converting JSON API responses to CSV makes data instantly usable for non-developers, accountants, marketers, and analysts who work in spreadsheets.
The converter automatically detects the union of all keys across all objects. Missing values become empty cells. This ensures every column gets represented and no data is lost, even when JSON objects have inconsistent structures.
