CSV to JSON Converter — Free Online Tool

What is CSV to JSON conversion?

CSV to JSON conversion transforms tabular data stored in Comma-Separated Values format into JavaScript Object Notation (JSON) format. CSV is a flat, row-based format commonly used in spreadsheets and databases, while JSON is a hierarchical, key-value format used extensively in web APIs, JavaScript applications, and modern databases like MongoDB.

When you convert CSV to JSON, each row in the CSV typically becomes an object in a JSON array, with the CSV header row providing the keys. For example, a CSV with headers "name,email,age" and a data row "John,john@example.com,28" becomes the JSON object {"name": "John", "email": "john@example.com", "age": "28"}.

Example: CSV to JSON conversion

Here's a practical example. Starting with this CSV data:

Name,Email,Department
John Smith,john@company.com,Engineering
Jane Doe,jane@company.com,Marketing
Bob Wilson,bob@company.com,Sales

The converter produces this JSON output (array of objects):

[
  {
    "Name": "John Smith",
    "Email": "john@company.com",
    "Department": "Engineering"
  },
  {
    "Name": "Jane Doe",
    "Email": "jane@company.com",
    "Department": "Marketing"
  },
  {
    "Name": "Bob Wilson",
    "Email": "bob@company.com",
    "Department": "Sales"
  }
]
