10+ Hacks To Uncover Hidden Matches: The Ultimate Guide To Finding Duplicates In Two Excel Columns
hack #1: Using the VLOOKUP Function
The VLOOKUP function is a powerful tool for identifying duplicate records in Excel. By using the VLOOKUP function, users can compare two or more columns of data and highlight any discrepancies.
For example, suppose we have a dataset with two columns: 'Name' and 'Email'. We can use the VLOOKUP function to compare these two columns and identify any duplicate records.
Here's an example of how to use the VLOOKUP function:
Cell A1: =VLOOKUP(A2, B:C, 2, FALSE)
Cell A2: =A1
By using the VLOOKUP function, we can identify any duplicate records in the 'Email' column and highlight them in the 'Name' column.
hack #2: Using the INDEX-MATCH Function
The INDEX-MATCH function is another powerful tool for identifying duplicate records in Excel. By using the INDEX-MATCH function, users can compare two or more columns of data and highlight any discrepancies.
For example, suppose we have a dataset with two columns: 'Name' and 'Email'. We can use the INDEX-MATCH function to compare these two columns and identify any duplicate records.
Here's an example of how to use the INDEX-MATCH function:
Cell A1: =INDEX(B:B, MATCH(A2, B:B, 0))
Cell A2: =A1
By using the INDEX-MATCH function, we can identify any duplicate records in the 'Email' column and highlight them in the 'Name' column.
hack #3: Using Conditional Formatting
Conditional formatting is a powerful tool for highlighting duplicate records in Excel. By using conditional formatting, users can quickly identify duplicate records and take action to eliminate them.
For example, suppose we have a dataset with two columns: 'Name' and 'Email'. We can use conditional formatting to compare these two columns and highlight any duplicate records.
Here's an example of how to use conditional formatting:
Home Tab > Conditional Formatting > Highlight Cells Rules > Duplicate Values
By using conditional formatting, we can quickly identify duplicate records in the 'Email' column and highlight them in the 'Name' column.
