Real Auditors Use Excel PowerPivot

powerpivot iconIf 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.

Auditors, Do Data Analytics or Die

Why You Must Validate Data

basic data analytics1Before you analyze data, you must first validate it.

Otherwise, your analysis may not be accurate, and you may miss some important insights or errors.

This post is part of the Excel: Basic Data Analytic series.

Before analyzing your data, you need to check the following:

  • Duplicate transactions do not exist.
  • Required fields/key fields do not contain blanks, spaces, zeroes, unprintable characters, or other invalid data.
  • Date fields contain real dates, and the range of dates is appropriate.
  • Amount fields don’t contain inappropriate zero, positive, or negative amounts, and the range of values is appropriate.

Review of ACL Excel Add-in, Now FREE!

In case you missed it, ACL released the next version of their Acerno product, renamed it ACL Excel Add-in, and made it FREE!

So I thought I’d update my review.

For my original review of Acerno, see A Review of ACL Acerno. It still seems that I’m the only one who ever took the time to review the product (versus marketing blurbs, which are all over the ‘net), which appears to be a statement regarding its popularity.

Despite the poor popularity, since they updated it AND made it free, I decided to dive in for another look.

Note: This add-in is not just for auditors! Any one who regularly reviews data should consider using this simple, EASY-to-use software.

Please take the new & improved poll at the bottom of this post (also free).
