In the ever-evolving landscape of data management and analytics, mastering Excel’s lookup functions is not just a skill but a cornerstone of efficient data handling. “Ultimate Excel with Power Query and ChatGPT” is more than just a book; it’s a guide crafted for data enthusiasts, Excel aficionados, and anyone aiming to harness the full potential of Excel’s lookup capabilities. This book embarks on a transformative journey through Excel’s lookup functionalities, navigating from the traditional methods to the trailblazing techniques that define the current era of data management. Each chapter unfolds a new dimension, debunking myths, unraveling complexities, introducing nested functions, and providing hands-on solutions to real-world data lookup dilemmas. By the end of each chapter, you will not only master the focused lookup function but also learn many other nested functions, expanding your knowledge of Excel. This book is divided into nine chapters. They will cover a range from Excel basics and basic lookup functions to the advanced use of AI in Excel. The details are listed below. Chapter 1: The chapter will introduce the basics of Excel. You will learn why you need to develop Excel skills and the general steps to follow to master these skills. We will explore the world of Excel formulas and functions, including nesting or combining functions. Additionally, we will cover the basics of Excel cell referencing and using Excel tables. Chapter 2: The chapter will introduce the most used Lookup function in Excel — VLOOKUP. It will highlight its challenges and provide a workaround to those challenges by showing how nesting other functions can help overcome VLOOKUP default settings. Chapter 3: The chapter will introduce a combo of functions that Excel users have come to regard as one lookup function — INDEX and MATCH. We will explore how the individual functions work and how their combination is the second most widely used method for looking up data. After that, we will investigate situations where this combo is better than the VLOOKUP function. Chapter 4: The LOOKUP function is as old as Excel itself. It has been there since 1985. Unlike its successor, VLOOKUP, the LOOKUP function has one unique feature — it can handle arrays. This chapter will investigate its usefulness 35 years later, particularly in areas where it is a better choice. Chapter 5: Apart from what Excel classifies as lookup functions, there are different ways of looking up data in Excel. This chapter investigates the different ways and functions that one can use to look up data. We will learn some rarely discussed methods, such as the use of Excel intersection, advanced filters, database functions, and the use of pivot tables. Chapter 6: Released in 2019, XLOOKUP was the most hyped release of any function. It was termed as the most powerful lookup function in Excel. The chapter will investigate scenarios where XLOOKUP could be the preferred lookup function. Chapter 7: Although it did not receive as much publicity as XLOOKUP, the FILTER function compensates for all the shortcomings in the previous lookup functions. This chapter will explore areas where FILTER is the ultimate lookup function. We will also look at its shortcomings and how to work around them. Chapter 8: Power Query has been hailed as the ultimate extract, load, and transform add-in for Excel, but it can also be used to look up data. This chapter will explore how Power Query can be used to create solutions for novice users who are afraid of tinkering with the functions. Chapter 9: This chapter will discuss how to incorporate artificial intelligence (AI) into solving lookup problems in Excel. We will explore topics such as what is ChatGPT and how can we get the best out of it. By the end of this chapter, you will be able to understand the nuances of prompting and leveraging ChatGPT for accurate and tailored responses.
