Excel expert David Ringstrom, CPA, shows you how to implement internal control features within your Excel spreadsheets in this empowering presentation. By using a simple invoice form as a teaching aid, he demonstrates several ways you can control users’ actions within an Excel spreadsheet, and how you can protect worksheets and workbooks from unauthorized changes.
David covers such topics as the IFNA, IFERROR, and ISERROR functions; the VLOOKUP function; the SUMIF function; the Data Validation feature; the Conditional Formatting feature; and hide and protect features.
David demonstrates every technique at least twice, first on a PowerPoint slide with numbered steps, and second in Excel 2016. He’ll draw to your attention any differences in Excel 2013, 2010, or 2007 during the presentation as well as in his detailed handouts.
Who Should Attend:
Practitioners seeking to simplify data entry, as well as those who develop spreadsheets for others to use and want to learn how they can prevent unauthorized changes.
