Working with CSV Files and Json Data

Introduction to Working with CSV Files and JSON Data

Handling data in CSV (Comma-Separated Values) and JSON (JavaScript Object Notation) formats is a common requirement in data science, web development, and many other fields. Python Training in Bangalore Both formats have their specific use cases and advantages. This guide will introduce you to working with CSV files and JSON data using Python, a versatile and powerful programming language widely used for data manipulation and analysis.

What are CSV and JSON?

CSV (Comma-Separated Values):

• Format: A simple text format for storing tabular data, where each row corresponds to a line in the text file, and each column is separated by a comma.

• Use Case: Ideal for storing and exchanging simple tabular data like spreadsheets or database tables.

JSON (JavaScript Object Notation):

• Format: A lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate. It is based on a subset of JavaScript programming language standards.

• Use Case: Widely used for data exchange between a server and a web application, as well as for configuration files and data storage.
