Without VBA…<\/p>\n

If you can use a helper column, you can use the MATCH<\/code> function to test if a value in one column exists in another column (or in another column on another worksheet). It will return an Error if there is no match<\/p>\n

To simply identify duplicates, use a helper column<\/strong><\/p>\n

Assume data in Sheet1, Column A, and another list in Sheet2, Column A. In your helper column, row 1, place the following formula:<\/p>\n

=If(IsError(Match(A1, 'Sheet2'!A:A,False)),\"\",\"Duplicate\")<\/code><\/p>\n

Drag\/copy this forumla down, and it should identify the duplicates.<\/p>\n

To highlight cells, use conditional formatting:<\/strong><\/p>\n

With some tinkering, you can use this MATCH<\/code> function in a Conditional Formatting rule which would highlight duplicate values. I would probably do this instead<\/em> of using a helper column, although the helper column is a great way to “see” results before you make the conditional formatting rule.<\/p>\n

Something like:<\/p>\n

=NOT(ISERROR(MATCH(A1, 'Sheet2'!A:A,FALSE)))<\/code><\/p>\n

\"remove_excel_duplicates\"<\/a><\/p>\n

For Excel 2007 and prior, you cannot use conditional formatting rules that reference other worksheets. In this case, use the helper column and set your formatting rule in column A like:<\/p>\n

=B1=\"Duplicate\"<\/code><\/p>\n

This screenshot is from the 2010 UI, but the same rule should work in 2007\/2003 Excel.<\/p>\n
