# Duplicates

edited 12/09/19

How do i create a formula that shows there are duplicates.

I would like it to have a check box in a column showing that "Sarah Jensen" has duplicate expense submission based off Consultant Name, Date of Receipt,Total Expense.

Hi,

Here is how I worked this request -

1. added a helper column to concatenate the fields that you are looking to compare, i.e. =[Consultant Name]@row + [Date of Receipt]@row + [Total Expense]@row
2. added a checkbox with the following formula =IF([Consultant Name]@row = "", "", IF(COUNTIF(Helper:Helper, Helper@row) > 1, 1, 0))
3. Hide the helper column

See the screenshot - I hope this helps?

You could skip the helper column and just include the additional column criteria in a COUNTIFS instead of a COUNTIF.

.

=COUNTIFS([Consultant Name]:[Consultant Name], [Consultant Name]@row, [Date of Receipt]:[Date of Receipt], [Date of Receipt]@row, [Total Expense]:[Total Expense], [Total Expense]@row)

This will count how many rows have the same data in those 3 columns as the row the formula is currently sitting on. In your screenshot, going down the rows it would populate

2

2

1

.

We can then leverage that result in an IF statement to check your box if there are any rows that have a number higher than 1 meaning there is more than one row with matching data.

=IF(COUNTIFS(..........) > 1, 1, 0)

.

So the finalized formula in the checkbox column would look something like this...

=IF(COUNTIFS([Consultant Name]:[Consultant Name], [Consultant Name]@row, [Date of Receipt]:[Date of Receipt], [Date of Receipt]@row, [Total Expense]:[Total Expense], [Total Expense]@row) > 1, 1, 0)
