CSV to JSON Converter — How It Works

This free online CSV to JSON converter parses CSV (Comma-Separated Values) data and converts it into a structured JSON array. The first row of your CSV is used as the property names (headers) for each JSON object.

Input Format

Your CSV should include a header row followed by data rows. Example:

id,name,email,active
1,Alice,alice@example.com,true
2,Bob,bob@example.com,false

Output Format

Each CSV row becomes a JSON object with the header names as keys:

[
  { "id": "1", "name": "Alice", "email": "alice@example.com", "active": "true" },
  { "id": "2", "name": "Bob", "email": "bob@example.com", "active": "false" }
]

Use Cases

• Converting exported spreadsheet data (Excel, Google Sheets) for use in APIs
• Transforming database exports into JSON for JavaScript applications
• Migrating data between systems that use different formats
• Seeding databases or test fixtures from CSV files
