Sorting a CSV file is one of the most common tasks when working with structured data. Whether you're organizing customer records, cleaning datasets, or preparing reports, sorting helps you quickly find and analyze information.

In this guide, you’ll learn different ways to sort a CSV file—manually and automatically—along with a smarter approach using a professional tool.

What is a CSV File?

A CSV (Comma-Separated Values) file stores tabular data in plain text format. Each line represents a row, and values are separated by commas.

Example:

Name,Age,City

John,28,Delhi

Anita,24,Mumbai

Raj,32,Bangalore
