What is a JSON to CSV converter?

A JSON to CSV converter turns JSON objects or arrays into comma-separated values. CSV is easier to open in spreadsheet tools, import into databases, and share with teams that do not work directly with JSON.

This converter supports nested data by flattening objects and joining arrays, so API responses and structured exports can become practical spreadsheet rows.

What this converter supports

  • JSON arrays, single objects, and NDJSON input.
  • Nested object flattening and array joiner configuration.
  • Comma, semicolon, and tab delimiter options.
  • CRLF or LF line endings.
  • Optional header row, alphabetized columns, and Excel BOM.

Common uses for this tool

  • Prepare API responses for spreadsheets.
  • Convert JSON exports into CSV reports.
  • Flatten nested records for Excel, Google Sheets, or BI tools.
  • Clean structured data before sharing with non-technical users.
  • Generate CSV from sample, pasted, or uploaded JSON data.

JSON conversion note

CSV is a flat table format, so deeply nested JSON may need flattening or simplified array values. Review the generated columns before importing important data into a spreadsheet, database, or reporting system.
