CSV vs Excel: When to Use Each File Format (Comparison Guide)

Understanding CSV and Excel Formats

CSV (Comma-Separated Values) and Excel (XLSX) are two of the most common formats for storing and managing tabular data. While they may seem similar at first glance, each format serves distinct purposes and offers different capabilities.

Key Differences Between CSV and Excel

File Structure

CSV files are simple text files that store data in a flat, tabular structure. Each line represents a row, with values separated by commas. Excel files, on the other hand, are binary files that can contain multiple worksheets, formatting, formulas, and various data types.

When to Use CSV Files

CSV files are ideal for:
