What is CSV data?

CSV (Comma-Separated Values) files are simple, versatile text files that store tabular data where each line represents a row, and values are separated by commas. These files are widely used for data storage and transfer because they're easy to create, read, and are compatible with most data processing tools and spreadsheet applications. CSV files can be opened and edited with basic text editors or more sophisticated programs like Excel, making them an accessible choice for data management.

Why would you want to remove duplicate rows or values from CSV data?

Cleaning and organizing CSV data by removing duplicates is essential for maintaining data accuracy and improving analysis quality. Here's why removing duplicates is crucial:

  • Ensures data integrity by eliminating redundant information
  • Reduces storage space and processing time
  • Prevents skewed analysis results from counting the same data multiple times
  • Improves reporting accuracy and decision-making
  • Simplifies data management and maintenance
  • Helps maintain consistent customer records and prevent double-counting
