CSV to JSON Converter for Python Developers

Browser Alternative to Python csv.DictReader

Python's csv.DictReader is the standard way to parse CSV to a list of dicts. Our browser tool gives you the same result instantly — paste a CSV string and get JSON without writing any code.

Python csv.DictReader Equivalent

import csv, json

with open('data.csv') as f:
    reader = csv.DictReader(f)
    data = list(reader)

print(json.dumps(data, indent=2))

Our tool performs the same operation — plus it infers types (numbers, booleans, nulls) that DictReader returns as strings by default.

Type Inference

• "42" → 42 (integer)
• "3.14" → 3.14 (float)
• "true"/"false" → true/false (boolean)
• "" → null
• Everything else → "string"
