The book explores the logic and features of Excel, starting with the basics and gradually moving to more advanced topics, including the most important mathematical, statistical, financial, lookup and reference, date and time functions, and more. Other features such as data analysis tools (Goal Seek, Solver, Scenario Manager), pivot tables, and macros are also covered. While the book is designed to be a valuable resource for students of all majors, its practical approach and gradual progression make it suitable for anyone who wants to acquire adequate skills in using Excel for both academic and professional purposes. To complete the learning process by developing real practical skills that can be applied in any context, the same authors have published Excel Workbook (4th edition, BUP, 2025). This book contains numerous exercises, each of which is accompanied by the corresponding initial and solved files, and many of which include detailed comments on how to carry out the tasks.
