Formula to compare two colums

I need to ensure that a person only attends a location once.

Can you advise on a formula which can check two columns of data,one with a unique code and the other with the location - That would identity if any duplicate area have been assigned to a person.

Person Location
A58 Tyrone
A58 Fermanagh
A66 Fermanagh
A66 Fermanagh

Eg A58 is fine as they are at different locations
A66 is a false return as the two locations are the same.

There are about 900 people to be checked and over 1000 different locations, each person could have between 1 -5 locations.

Any help would be appreciated.
Thanks

Hi Julie,

Thank you for the forum question.

You can use a COUNTIFS function.

Add a new column. If you have the unique code in the range A2:A200 and the location in the range B2:B200 and want the to find duplicates in column C the function should look like this:

=COUNTIFS($A$2:$A$200,A2,$B$2:$B$200,B2)

Copy the function down and if the function return 1 the record is unique otherwise it will display how many duplicates of the record you have.


Kind regards

Excel tip:

Hide columns in an Excel 2010 Worksheet

If you don’t want part of the Excel worksheet to be visible or when you don’t want certain data to appear in print outs, then a simple solution is to temporarily hide a column or multiple columns.

Hiding a single column:

1)Right click on the column header of the column you want to hide (this is the grey bar along the top edge of the worksheet)
2)Choose Hide from the menu
3)This column will now be hidden from view

Hide more than one column:

1)In the column header drag select to highlight the columns you want hidden
2)Right click and choose Hide from the menu
