What Is JSON to CSV Conversion?

JSON (JavaScript Object Notation) is commonly used in APIs and applications, while CSV (Comma-Separated Values) is widely used for spreadsheets, reporting, and database imports.

This tool transforms structured JSON data into flat CSV format for easy data handling.

Why Convert JSON to CSV?

JSON is ideal for APIs and applications, while CSV is better for:

  • Excel & spreadsheet import
  • Database uploads
  • Data reporting
  • Analytics tools
  • CRM systems

This tool helps developers quickly transform API responses into spreadsheet-ready CSV files.

Example JSON Input

[
  {
    "id": 1,
    "name": "John",

  },

    "name": "Sara",
    "email": "sara@example.com"
  }
]
