How to Convert JSON to CSV - Step by Step Guide

Step 1

Input Your JSON Array Data

Start by adding your JSON array data that needs to be converted to CSV format. The tool works best with arrays of objects.

Example: Try This JSON Array Data

Copy and paste this JSON array example to see conversion: 📊

[
  {
    "productId": 1001,
    "productName": "Wireless Mouse",
    "category": "Electronics",
    "price": 29.99,
    "inStock": true,
    "supplier": "TechCorp"
  },
  {
    "productId": 1002,
    "productName": "USB Keyboard",
    "category": "Electronics",
    "price": 49.99,
    "inStock": false,
    "supplier": "KeyboardPlus"
  },
  {
    "productId": 1003,
    "productName": "Monitor Stand",
    "category": "Accessories",
    "price": 79.99,
    "inStock": true,
    "supplier": "DeskMaster"
  }
]
Step 2

Configure CSV Options

Customize how your JSON array is converted to CSV format! ⚙️ Choose headers, delimiters, and formatting options.

•
Automatic headers: Extract column names from JSON object keys
•
Custom delimiters: Choose comma, semicolon, tab, or custom separators
•
Nested object flattening: Handle complex JSON structures
•
Data type preservation: Maintain numbers, booleans, and strings
Step 3

What is JSON to CSV Conversion? 🔄

JSON to CSV conversion transforms JSON array data into comma-separated values format, making it compatible with spreadsheet applications, databases, and data analysis tools. This process flattens JSON objects into tabular rows and columns, with object keys becoming column headers and values becoming data rows.

The conversion handles nested objects, arrays, and different data types, creating clean, structured CSV files that maintain data relationships while providing universal compatibility with data processing tools.

Frequently Asked Questions

What JSON format works best for CSV conversion?

JSON arrays containing objects work best for CSV conversion. Each object becomes a row, and object keys become column headers. Single JSON objects create key-value pair tables, while arrays of primitive values create single-column CSV files. You can also visualize JSON as tables before converting to CSV.

How are nested JSON objects handled in CSV?

Nested objects are flattened using dot notation (e.g., "address.street") or converted to JSON strings within CSV cells. Arrays within objects are typically converted to comma-separated values or JSON strings to maintain data integrity.

Can I customize the CSV delimiter and format?

Yes! You can choose different delimiters like comma, semicolon, tab, or pipe characters. The tool also supports custom quote characters and escape sequences to handle special characters in your data properly.

Will the CSV work with Excel and Google Sheets?

Absolutely! The generated CSV files follow standard RFC 4180 format and work perfectly with Excel, Google Sheets, LibreOffice Calc, and other spreadsheet applications. Data types and formatting are preserved where possible.

Can I convert large JSON files to CSV?

Yes! The converter handles large JSON files efficiently by processing data in chunks. Very large datasets are streamed to maintain performance while generating accurate CSV output without memory issues.

Is the JSON to CSV converter free to use?

Yes, completely free with no limitations on JSON file size, conversion frequency, or output features. No registration required, and you can convert unlimited JSON data to CSV format at no cost.
