csv-to-json v1.0.0

A lightweight, zero-dependency CSV-to-JSON converter for AI agents and developer workflows.

Highlights

• Type inference: Automatically converts CSV values to appropriate JSON types (int, float, bool, null)
• Nested key expansion: Dot-notation headers like user.name become nested JSON objects
• Streaming support: Process large CSV files record-by-record without loading everything into memory
• Flexible input: Accepts file paths, raw CSV strings, or stdin
• CLI + library: Use from the command line or import directly into Python code
• Zero dependencies: Uses only Python 3.10+ standard library

Quick Start

python src/csv_converter.py data.csv -o output.json

from src.csv_converter import csv_to_json
result = csv_to_json("data.csv")
