CSV to JSON Converter

About CSV to JSON Converter

This tool converts CSV (Comma-Separated Values) data into JSON arrays. Each row becomes an object, with the first row used as property names.

Features

• Auto Type Detection: Numbers and booleans are automatically converted from strings
• Custom Delimiters: Support for comma, semicolon, or tab-separated values
• Quoted Values: Properly handles quoted values with commas or newlines
• Pretty Output: JSON is formatted with proper indentation

How It Works

1. The first row is treated as column headers
2. Each subsequent row becomes a JSON object
3. Header values become object property names
4. Cell values are automatically typed when possible

Example

name,age,active
Alice,30,true
Bob,25,false

Converts to:

[
  {"name": "Alice", "age": 30, "active": true},
  {"name": "Bob", "age": 25, "active": false}
]
