Excel expert David H. Ringstrom, CPA, shows you how to identify and manage duplicate data within your spreadsheets in this live Microsoft Excel training. He covers a variety of topics, including identifying duplicate data visually by way of the Conditional Formatting feature, using a pivot table to determine how many duplicates are in a list, and applying worksheet functions like SUMIF or COUNTIF to sum or count instances of duplicates.
In addition, David explains how to use the MATCH worksheet function to help you identify discrepancies in two different lists, how VLOOKUP will stop searching for duplicates after an initial match in found within a list, and how to use Excel’s Data Validation feature to create a rule that ensures users can’t enter the same data more than once in a given area of a spreadsheet.
