Summary

The M language is the backbone of Microsoft Power Query’s data transformation capabilities. M is widely used within the larger Microsoft ecosystem, including a variety of software applications and web-based services. Many different types of data professionals can benefit from learning M to efficiently and effectively ingest and transform data across a wide range of scenarios. By mastering M, you gain the ability to efficiently handle complex data transformations, customize your data workflows, and optimize performance, thereby tapping into the full potential that Power Query has to offer you for your data manipulation needs.

In this chapter, we have covered the essential questions of who, what, where, why, and how M is used, as well as provided a brief introduction to the fundamental aspects of the M language. In the next chapter, we introduce you to the primary interface in which you will be writing and working with M.
