The Advanced Editor provides a powerful way to customize and fine-tune your data transformations beyond the capabilities of the standard user interface. It allows you to write custom M code to implement complex data transformations, or to modify the code generated by the user interface to achieve more specific goals.
Select the query you want to edit to access the Advanced Editor, and then click the Advanced Editor button in the ribbon. This will open a new window that displays the M code for the selected query.
In the Advanced Editor, you can modify the M code as needed using a range of syntax highlighting and editing tools. You can also use the IntelliSense feature to suggest syntax and provide helpful hints as you write your code.
The Advanced Editor is particularly useful for experienced Power Query users who are familiar with M code and want to take advantage of its full power and flexibility. However, it is also possible to learn M code and use the Advanced Editor to implement custom data transformations even if you are not an experienced programmer.
Overall, the Advanced Editor in Power Query Editor provides a powerful way to customize and fine-tune your data transformations, making it a valuable tool for advanced users and data professionals.
Power Query Editor’s Advanced Editor lets you see the code it creates at each step. You can also create your own shaping code. From the ribbon, select View, then Advanced Editor. The existing query code appears in a window.
