JSON to CSV

This free online JSON to CSV Converter tool helps you easily transform complex JSON data into clean, structured CSV format. Whether you're a developer working with APIs, a data analyst dealing with nested datasets, or just someone trying to make sense of structured data, this tool is designed to save time and simplify your workflow.

What is JSON?

JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It's commonly used for transmitting data in web applications, especially when working with APIs.

A typical JSON object might look something like this:

{
  "user": {
    "id": 123,
    "name": "Alice",
    "email": "[email protected]",
    "contact": {
      "phone": "123-456-7890",
      "address": {
        "city": "New York",
        "zip": "10001"
      }
    }
  }
}

Why Convert JSON to CSV?

While JSON is great for structured data exchange, it's not the easiest format for analysis or visualization, especially in spreadsheet tools like Excel or Google Sheets. CSV (Comma-Separated Values), on the other hand, is simple, flat, and widely supported. Converting JSON to CSV allows you to:

• Import data into spreadsheet software
• Perform analysis with tools like Excel or pandas (Python)
• Easily view and manipulate nested data
• Make reports or share data in tabular format

How it works?

See the examples below to understand how it handles different nested and complex JSON data.

Example 1

{
  "user": {
    "id": 1,
    "email": "[email protected]",
    "contact": {
      "phone": "555-1234"
    }
  }
}

Output

Example 2

{
  "user": {
    "id": 123,
    "name": "Alice",
    "emails": ["[email protected]", "[email protected]"],
    "contact": {
      "phone": "123-456-7890",
      "address": {
        "city": "New York",
        "zip": "10001"
      }
    }
  }
}

Features

The tool is packed with features to give you full control over how your JSON data is transformed:

1️⃣ Target Path

It helps you convert a specific part of the JSON to CSV format. For example, if you only want to convert the contact details of the user object to CSV, you can set the target path to user.contact.

2️⃣ Array Handling Options

JSON arrays can be tricky, especially when they contain nested objects. Choose how arrays should be handled:

• Flatten: Each array item becomes a separate row
• Join: Combine array items into a single column, separated by commas

3️⃣ Custom Headers

Define your own CSV headers to rename the default csv headers.

user_id: id
user_contact_phone: phone
user_email: email

4️⃣ File Upload & URL Support

The tool supports two methods of input -

1. Upload a .json file directly from your device
2. Paste a URL — the tool will fetch and convert the JSON response for you
