This comprehensive guide will help you understand everything about CSV files, how our viewer works, and how to maximize its potential for data analysis.

CSV files are widely used because they're lightweight, human-readable, and compatible with virtually all spreadsheet and database applications.
Key Point: CSV files are platform-independent and can be opened by Excel, Google Sheets, databases, and programming languages without proprietary formatting constraints.
