My blog comes of age this week as it hits the big 4-0! I am feeling quite empowered, so that gives me an idea! In M-Powered, I described how to get to a description of the functions that can be used in M code to manipulate data by accessing the Microsoft help pages. There is however another way to get to the functions. Let me show you....

This function returns the number of combinations (with repetitions) for a given number of items.

Are you often COMBIN the Excel functions to see how many subsets you can make? This function returns the number of combinations for a given number of items (i.e. the number of distinct subsets of items where order is unimportant). You should use COMBIN to determine the total possible number of groups for a given number of items.

In Pivotal Pivoting, I showed how easy it was to pivot columns. When I pivoted my expense code column to show the amounts for each expense code, I had a table with lots of null values in it, as shown below. I am going to use this table to show how I can sum columns where some values are null...

Last Friday, we posed perhaps one of the hardest challenges that we’ve had so far: can you create a file that will refresh your Power Query queries, and pop up a message box letting us know when it’s finished?

Welcome to this month’s Final Friday Fix! The inspiration for this month’s challenge comes from an actual problem that we’ve been trying to solve for some client work, that we couldn’t find an answer to anywhere online. But first, let’s talk about refreshing queries – that is, Power Query queries in particular. ...

In Power Query, explore the ‘Structured Column’ section on the ‘Transform’ tab, which is not available for most column types.

This is one of the pillars of Excel’s features. Yes, the jokes get no better...

Last week we spoke about ranges and how you can refer to them in different ways. This week, we’re going to look at some of the ways you can apply range modifiers to change what set of cells exactly you’re referring to.

Power Query’s ability to efficiently transform data allows one to pivot (and unpivot) data at the touch of a button.
