Summary
In this chapter, we have highlighted practical aspects of data manipulation and preparation by focusing on two very different topics: extracting fixed patterns and combining data from multiple Excel files. Although they feel worlds apart, these skills, among many others, are both essential for transforming raw data into insightful, actionable information.
By breaking down processes into manageable pieces, underscoring the importance of a methodical approach as well as creative problem-solving, we aimed to offer a collection of ideas, fuelling your imagination to tackle any challenge. The next chapter focuses on another critical area: optimizing performance. You will learn about factors that influence, and methods to improve, query performance.
