Answer:

Data cleaning and transformation involve a combination of techniques such as building VLOOKUP or XLOOKUP functions, creating pivot tables, crosstabs, charts, or graphs, and deleting columns or adding calculations to an Excel spreadsheet.

A form of data cleaning and transformation involves utilizing various Excel functions and features to organize, analyze, and present data more effectively. This process can include building VLOOKUP or XLOOKUP functions to retrieve and consolidate data from multiple worksheets, making it easier to access and analyze relevant information.

Another useful method for data transformation is constructing pivot tables, crosstabs, charts, or graphs, which help in summarizing and visualizing data trends, patterns, and relationships. These tools enable users to examine and manipulate large datasets quickly, making it easier to draw meaningful conclusions and make data-driven decisions.

Additionally, data cleaning can involve deleting unnecessary columns or adding calculations to an Excel spreadsheet. This step helps in streamlining data by removing irrelevant or redundant information and introducing new, meaningful insights through mathematical operations and formulas.

In summary, data cleaning and transformation involve a combination of techniques such as building VLOOKUP or XLOOKUP functions, creating pivot tables, crosstabs, charts, or graphs, and deleting columns or adding calculations to an Excel spreadsheet. These methods enable users to efficiently organize, analyze, and present data, ultimately leading to better decision-making and improved outcomes.
