Filter even or odd rows in Excel

This morning I pasted a list of values into Excel in which the pattern consisted of a “good value” followed by that same value with a minor adjustment. The second, near-duplicate value wasn’t useful to me so I wanted to filter out all even rows so I’d just have the first of each near-duplicate.

I say near-duplicate because if your values truly are duplicates, you can just use the Remove Duplicates function.

So to filter odds and evens, we’ll add a new column to the right of our data and set the formula to:

=ISEVEN(ROW())

This evaluates the data’s row number as even or odd and will return TRUE if the number is even or FALSE if not. Double-click the handle in the lower right of the cell to fill down.

Then we filter the column for just TRUE (evens) or FALSE (odds). You can right-click the value you want to keep > Filter > Filter by Selected Cell’s Value
