The Power Query Editor is a powerful tool for transforming data. It can be used to filter and clean data, combine data from multiple sources, and apply transformations to the data.
For example, if you have a data set with multiple columns of customer data, you can use the Power Query Editor to filter out any rows that don’t meet certain criteria, such as customers who live in a certain area. You can also use the Power Query Editor to combine data from multiple sources, such as a customer database and a sales database, and apply transformations to the data, such as calculating the average sales for each customer.
