finding unique values

[waylonk]

I have a spread sheet with 4 columns and 900 rows I am trying to identify the
rows that do not contain a duplicate amount. For example I have rows with

100
100
97
97
96
96
98
101

I am trying to pull the list of 98 and 101. The spreadsheet is a list of
invoices paid vs invoices unpaid if it is paid there are two rows with the
same data if it is unpaid there is only one row. I am trying to find the
unpaid invoices.

One simple method would be to sort the worksheet by your primary data and
then put:

=if(a2=a3,"X","")

in a helper column. All parts with blanks would be non-duplicates

If the above numbers are in column A from row 1 to row 900, try the
following formula in cell E1:

=IF(COUNTIF(A$1:A$900,A1)=1,"X","")

Copy this down column E to row 900.
There will be an "X" on those line with a unique number.

Hope this helps / Lars-Åke
