How can data be transformed in Power BI using the Query Editor?

In Power BI, the Query Editor provides a range of functionalities for transforming data. After loading the data, it becomes visible in the Fields Tab. From here, we can modify the datasets using the Query Editor, regardless of their data source.

One way to transform data is by renaming a dataset or removing single or multiple columns. This can be done easily in the Query Editor. By clicking the Edit Queries button on the Home Ribbon, we can access the Query Editor and perform these manipulations.

Another transformation that can be done is creating a custom column. For example, using financial data, we can shape the data to meet our needs by creating a custom column called New Manufacturing Price. This column can be defined using formulas and can be based on existing columns.

Changing the data types of columns is also possible through the Query Editor. For instance, if a column has a floating-point data type, we can easily adjust it to a whole number.

Moreover, the Query Editor provides the option to remove columns that are not adding value to the dataset. By selecting the column and choosing the Remove Columns option, we can easily eliminate unnecessary columns from the dataset.

Additionally, the Query Editor offers other functions such as adding and removing rows, transposing data, pivoting, and splitting. These functions can be easily performed within the Query Editor.
