Power Query How is an online reference site focused on the Microsoft Power Query M language, rather than a traditional structured course platform. The text shows that it covers data transformation, data preparation, and ETL scenarios in Power Query M, organizing materials such as functions, enumerations, constants, dynamic values, and type values. It also states that the guide is updated regularly to reflect changes in Microsoft products.
Judging from its content structure, its main value lies in quick lookup and supplementary understanding. Functions are organized by categories such as Accessing Data, Table, Text, Date, List, Number, Record, Binary, and Error Handling. Each M function typically includes syntax, related articles, and often examples. Some Updated Articles claim to include original examples that differ from Microsoft’s documentation. However, the crawled text does not show live classes, recorded courses, 1-on-1 tutoring, assignments, learning progress tracking, or cohort-style services, so it is better suited as reference documentation rather than a complete learning path.
The page does not show subscriptions, course prices, or paywall information, so within the scope of the crawled text, the content appears to be mainly free to access. The teaching/content language is English. The site is part of the BI Gorilla project, created and maintained by Rick de Groot. It also integrates information from Microsoft’s official documentation and follows a similar reference-site model to dax.guide. No certification, completion certificate, or official authorized training information was found.
Its strengths are its focused topic and broad coverage, making it especially useful for Power BI, Excel, and Microsoft 365 users who need to look up syntax, parameters, enumeration shorthand, and type definitions while writing M code. Its connection with official documentation also improves credibility. The downside is that learning support is limited: some function pages explicitly state that no additional documentation is available, so content depth may be uneven. It also lacks Chinese explanations, interactive Q&A, practical projects, and a certificate system.
It is suitable for data analysts, BI developers, and advanced Excel users who already have some Power Query foundation and want to improve their efficiency when working with the M language. Complete beginners may still need to combine it with Microsoft Learn, official Power BI documentation, or Chinese video tutorials. The crawled text cannot confirm access conditions from China, and there is no information about network connectivity or payment methods. Since no paid step is shown, payment is not a major barrier. If access is unstable, Microsoft’s official documentation, the Power BI community, and Chinese Power Query tutorials can serve as alternatives.
