Understanding the differences between the two formats and knowing how to convert JSON to CSV can unlock a world of possibilities for data manipulation and analysis.

Understanding JSON and CSV formats

What is JSON?

JSON is a lightweight data-interchange format that is human-readable and easy for machines to parse and generate. It is primarily used to transmit data between a server and a web application as an alternative to XML (eXtensible Markup Language). JSON organizes data into key-value pairs, providing a flexible and intuitive structure for representing complex data structures.

What is CSV?

CSV, on the other hand, is a plain text format that stores tabular data (numbers and text) in a simple, row-based structure. The values in each row are separated by commas, hence the name Comma-Separated Values. CSV is widely supported by spreadsheet software and databases, making it a popular choice for data exchange within and between various applications.

Why convert JSON to CSV?

Converting JSON to CSV offers several benefits that make it worth considering. Firstly, CSV files have a smaller file size compared to JSON files, making them easier to store and transfer.
