If you’re an auditor and you are not yet using Excel PowerPivot, you are missing the next greatest thing since spreadsheets arrived.
If you are NOT an auditor, and you don’t use PowerPivot, you’re in the same boat with the auditors mentioned above, and it is sinking.
In other words, if you use Excel, you should be learning Excel PowerPivot. It’s that big.
Let me explain why.
NOTE: I updated this post quite a bit with new info…
If you’re an auditor, you need data analytic skills or you will die.
Or put another way, if you don’t acquire them in the next 1-5 years, you will no longer be an auditor.
Pretty bold statement, isn’t it?
Today I was adding a new table to a scripted ACL project and kept getting an error.
This project automatically opens a folder on the LAN, reads the files in the folder, and loads all of them.
All I did was add one more file to the folder. ACL refused to load that one file.
Whether you script your projects or use menu commands, you need to review your ACL log carefully.
Good analysts review their results and the log as they work in ACL, after they think they are done, and have others review their log before the ACL project is relied upon.
(You can’t imagine the dumb mistakes my team and I found that saved us a lot of embarrassment later.)
You can easily use Excel’s Flash Fill tool to transform data fast, without formulas.
Did you catch that? Without formulas!
Flash Fill has been around a few years, but few people, including auditors, seem to be aware of it.
This tool is so easy to use, you could learn it AND teach it to your mom in 4 minutes. Really.
If you like Dilbert cartoons or big data, you might enjoy Dilbert’s adventures in data analysis, data mining, data privacy, security, and dealing with a dumb manager.
As I explained in the last Excel post, you can check for blank and invalid data in Excel several ways.
In this post, I will focus on the insights and issues encountered by sorting each column from A to Z and then Z to A.
Sounds pretty simple, but I’m willing to bet you will be surprised to learn a thing or two…
