PowerQuery uses queries as its name implies. PowerQuery uses the Data Model, a feature that exists but is not exposed in Excel for Mac.
In Excel for Mac you can use Microsoft Query to make a PivotTable using multiple worksheets from an Excel workbook as your data source.
"Easy" is a relative concept. Yes, it is easy once you know how to do it. The first time through will be the most difficult, but once you see how all the pieces fit together, you will be able to run your queries with little to no difficulty.
Knowing Visual Basic for Applications is not required. Just so you know, you can automate your query process with VBA, AppleScript, Objective-C, or Javascript, but it is certainly not required or necessary to use any of these languages.
Knowing Structured Query Language (SQL) at least at a beginner level is essential.
Installation of add-ins is not required. The ability to perform SQL queries is already built into Excel. You will not need any add-ins.
On the Mac side, the infrastructure required to preform ODBC connections is no longer included with Mac OS. ODBC drivers and the ODBC manager application were casualties of making Mac OS free. Now, only people who want these connections and are willing to
pay for them have them. The price is quite small, IMHO. You will need to install the
**ActualTech Access driver**. Installing the driver also installs the new 64-bit ODBC manager application to your Applications > Utilities folder. The driver costs $39.95 US. There is a free trial
that you can use. It works the same as the full version, but returns only the first 5 or so records of your query.
