Write a custom filter
Is it possible to write a custom filter, either in VBA or just normal Excel filtering functions, rather than using the pre-existing ones in Excel? For example, in Excel you can hide / filter out dupl...
Depends on what your requirement is, are you filtering out duplicate entries in a single column or in a combination of columns?
If a single (and lets assume the data is in cells A2:A100), you can add a column and use a formula like this to count the # of times an item occurs: =COUNTIF($A$2:$A$100,A2)
Then you simply filter your table for that new column on the value 1

- Thank you. So this will basically add an additional column which shows if a specific value - the value in cell A2 - occurs in any other cell in that column. That would certainly be a good start, but I would have to then run it for every call value in that column, to catch all the duplicate. Is there some more generalizable way? For example, what if each cell made a relative reference to the cell one space to its left?
