CSV to JSON Converter

This is a Python script that converts CSV files to JSON format. It supports automatic encoding detection, recursive directory traversal, and various customization options for the output JSON.

Features

• Convert individual CSV files to JSON.
• Convert all CSV files in a directory (with optional recursion into subdirectories).
• Automatically detect the encoding of CSV files.
• Option to prevent overwriting existing JSON files.
• Option to output compact JSON (not pretty-printed).
• Verbose mode for detailed output.

Requirements

• Python 3.x
• chardet library

You have to install required library for automatic file extension or encode detection using pip:

pip install chardet
