  • Combining Data From Multiple Excel Workbooks With Power Query–The Easy/Complete/Power BI Ready Way!

    In a series of multiple blog posts within the last few weeks, a lot of blog authors (Ken Puls, Chris Webb, Mike and many others) who I follow have raised the enthusiasm for combining multiple Excel Workbooks or even worksheets into a single table.

    All of our approaches have two things in common:

    • Calling a Function
    • Refer to a single type of object (most of the time it’s just a Worksheet)

    wich may not the best or most complete way to work with Power BI (on the cloud) since queries that refer to a function can not be refreshed on the cloud and also because you might want to combine sheets, tables and named ranges at the same time .

    Note that If you try refreshing a workbook that contains a Query with a function on Power BI, you’ll get an error similar to this:

    PQFunctionAndDMG

    So, what if you could create a query that can combine anything and everything from multiple workbooks? Sonrisa READ THIS POST and you’ll see how

  • Getting API results from Azure Machine Learning into Power Query

    If you are into cool new technologies then this blog post is for you.

    A few weeks ago, Microsoft released a new service called Azure Machine Learning or simply #AML. It’s a cloud service that let’s you create experiments for data prediction and machine learning in general. (What Data Scientists do)

    You can read more about this service here (you can try it for FREE!!). What really has me hooked to this is the fact that it you can integrate r, so you can create your R code and even packages and use them on the cloud without doing anything special – an enfortless system bound to make things happen (or predict what would happen).

    This type of service is the one that saves hundreds of hours of development or tedious coding so I recommend you give it a try Sonrisa

    This blog post is based on this sample experiment

    We have the experiment ready – let’s use the API and grab some results with Power Query!
