JSON vs CSV: Which One Should You Use for Your Data Needs? or JSON vs CSV: What Are the Key Differenc

Quick answer: CSV for simplicity, JSON for complexity.

Real-world example: I once had to store product catalogs with variants (sizes, colors, etc.). CSV was a disaster—JSON handled it perfectly.

For tools, `Excel`/`Google Sheets` for CSV, `Postman` or `Insomnia` for JSON APIs.

And no, JSON isn’t always heavier. If your CSV has repetitive headers or sparse data, JSON can be leaner.
