Why Convert CSV Files to JSON?

Comma-Separated Values (CSV) are widely used for exporting tables from programs like Microsoft Excel or Google Sheets. However, modern web applications, RESTful APIs, and NoSQL databases natively consume JSON because of its hierarchical structure and ease of parsing.

Readability: JSON represents objects in a clear, nested key-value format.
Compatibility: Easily integrates with JavaScript frontends and backend services.
Flexibility: Handles arrays and structured objects far better than flat tables.
