Introducing Data from Hell:
Watch out, its data from hell. In this new video series, we are going to examine some nutty, frustrating and fun data reshaping challenges and solve them using Excel. We will use Power Query, Formulas, VBA or other features as needed to free this data from damnation.
For our first installment, let’s reshape unevenly spaced list of values to a table.Continue »
Last week, we talked about how to copy and paste visible cells alone (ie exclude any filtered rows or hidden columns etc.) In the comments section many of you suggested two more ways to deal with this annoying problem. Let’s take a look them.Continue »
Here is something annoying with Excel.

Recently, I had to make a bunch of panel charts. After wrangling with Excel (and a tiny bit of VBA) to create them, I wondered if we are suffering needlessly by being too loyal to Excel. I switched to R and could create these panel charts in almost no time (well, first I had to learn how to pivot the data using dplyr). Today, let me share the experience.Continue »
