What is JSON to CSV?

A tool that instantly converts JSON format data to CSV format. Automatically transforms complex hierarchical JSON into flat CSV tables that are easy to work with in Excel or Google Spreadsheets.

Streamlines development and data analysis tasks such as analyzing API responses, processing datasets, and transferring data between systems.

How to Use

Enter JSON data in the left input area and it will automatically convert to CSV format, displaying the result on the right. Save the conversion result using the "Download CSV" button.

Conversion Options

With Header

• Enabled (Default) - JSON key names are output as headers in the first row, making data content easier to understand
• Disabled - Only data is output without header rows

Use Cases

• API response analysis - Convert JSON data from REST APIs to CSV for analysis
• Data cleansing - Transform complex JSON structures into organized CSV format
• Cross-system data migration - Easily convert data between different formats
• Report generation - Quickly create CSV reports from JSON data
• Debugging support - Transform complex JSON data into a more visually comprehensible format

How Conversion Works

JSON to CSV conversion follows these steps:

1. Each JSON object corresponds to one CSV row
2. Nested objects are expanded using dot notation like "parent.child"
3. Arrays are expressed as comma-separated values or expanded into multiple rows
4. Each key becomes a column name (header) in the CSV

About JSON and CSV

What is JSON?

JSON (JavaScript Object Notation) is a lightweight format for representing structured data.

• Flexible data structures composed of key-value pairs
• Supports hierarchical (nested) structures
• Diverse representation using objects ({}) and arrays ([])
• Widely used in APIs and configuration files

{
  "name": "John Smith",
  "age": 30,
  "skills": ["HTML", "CSS", "JavaScript"]
}

What is CSV?

CSV (Comma-Separated Values) is a simple format for representing tabular data.

• Each line represents a data record
• Fields are separated by commas
• First line often used as header (column names)
• High compatibility with spreadsheet programs like Excel

name,age,email
John Smith,30,example@example.com
Jane Doe,25,jane@example.com

Benefits of Conversion

• Visualize complex JSON data in tabular format
• Easy editing and analysis with spreadsheet software
• Simplified database imports
• Smooth data sharing with non-technical users
