CSV to JSON Converter

CSV to JSON Converter

This free tool converts CSV (Comma-Separated Values) data into a JSON array of objects. The first row of your CSV is used as the header (keys), and each subsequent row becomes a JSON object.

How to Convert CSV to JSON

1. Paste your CSV data into the left text area (include the header row).
2. Click Convert.
3. Copy the JSON array from the right text area.

Example

Input CSV:

name,age,city
Alice,30,London
Bob,25,Paris

Output JSON:

[
  { "name": "Alice", "age": 30, "city": "London" },
  { "name": "Bob", "age": 25, "city": "Paris" }
]

FAQ

Are numbers and booleans detected automatically?

Yes. Values that look like numbers or booleans (true/false) are automatically converted to their correct JSON types.

Is my data private?

Yes. Everything runs in your browser. Your CSV never touches our servers.
