How To Validate Data Against Online Lists Using M

Most data problems in Power Query can be solved using the UI, and even more can be resolved by slightly editing the M code generated by the UI. Thus, if your data is not excessively messy and your transformations aren’t too intricate, you may not require extensive M knowledge. However, if you invest time in learning M, you can unlock incredible possibilities!

Learning M language is going to be advantageous for anyone who works with data and wants to efficiently manipulate, clean and transform large and complex data sets. In this video, Brian is going to demonstrate exactly why that is the case, featuring an impressive solution by Alexis Olson in one of Excel BI’s recent challenges wherein he was able to automate the comparison of your data against online lists and references.
