Excel Explained: Internal Control
In this session Excel expert David Ringstrom, CPA shows you how to implement internal control features within your Excel spreadsheets.

David will use a simple invoice form as a teaching aid to show various ways to control users actions within an Excel spreadsheet, as well as protect worksheets and workbooks from unauthorized changes.

David will teach from primarily from Excel 2010, but will demonstrate new features in Excel 2013 when warranted, as well as disclose any differences in Excel 2007. Coverage of Excel 2003 will be limited to questions raised by the audience.

Covered Topics

  • See how to arrange two worksheets from within the same workbook onscreen at the same time
  • Improve the integrity of spreadsheets with Excel’s VLOOKUP function
  • Compare and contrast IFNA, IFERROR, and ISERROR, and see which versions of Excel support each of these worksheet functions
  • Create an in-cell list by way of Excel’s Data Validation feature
  • Restrict users to entering dates within a given range, or before/after a given date
  • Use the Table feature (List feature in Excel 2003) to have supporting formulas automatically update themselves when your database query results change
  • Specify a range of whole numbers that a user can enter in a worksheet cell
  • Make it harder for users to circumvent data validation, and easily identify when they attempt to do so
  • Toggle the Locked status of a worksheet cell on or off by way of a custom shortcut

Learning objectives:

  • Use look-up formulas to look up data automatically from lists
  • Use Excel’s Table feature to future-proof elements of your spreadsheet
