Instructor for this course

Learn from Excel expert David Ringstrom, CPA, valuable techniques that can be used to verify the integrity of even the most complicated Excel spreadsheets. In this comprehensive course, David shows you how to use Excel’s formula auditing and error-checking tools, identify duplicates in a list, monitor the ramifications of even minor changes made to your workbooks, use the Evaluate Formula feature, and much more.

David demonstrates every technique at least twice: first, on a PowerPoint slide with numbered steps, and second, in Excel 2016. He draws your attention to any differences in Excel 2013, 2010, or 2007 during the presentation as well as in his detailed handouts. David also provides an Excel workbook that includes most of the examples he uses during the webcast.

  • Identifying duplicates in a list using Conditional Formatting.
  • Selecting all formulas within a worksheet with just two mouse clicks.
  • Adding a macro to Excel that adds the ability to display any formula in a cell comment.

  • Protecting sensitive information by marking key worksheets as VeryHidden.
  • Transforming cell references into range names by way of the Apply Range Names to Formulas command.
  • Differentiating between manual and automatic calculation modes in Excel, and when Excel may default into manual calculation mode.
  • Understanding the purpose and nuances of Excel’s Personal Macro Workbook.
  • Bringing Excel’s green error-checking prompts under control by managing the underlying rules.

Very good course overall and definitely learned some good tips and tricks. Only minor suggestion would be to either mention or discuss the comment macro earlier in the presentation only because I was wondering during the first portion of the presentation how that was actually being done. Thank you for providing the step by step on how to enable and now that I have it set up I plan on using it going forward.

Overall, the course was very helpful in learning some of the useful ways to assess the standing of a workbook, particularly as either the main user of the document or someone in a review capacity. A few of the topics, such as the macros, were probably meant for a course where the main function was complex uses.

There were some very cool things in this course like embedding notes within formulas and creating macros to add cell formulas to comments box. This was a very helpful course for auditing workbooks and full of great gems.

I have over 20 years of working in Excel, so some of this was not new. There were some different items that I was not aware of that is very helpful.

Great course. For the final 3mins the dataset was not provided so I could only follow along onscreen instead of working through the excel.
