My data is like this
````
cell A1: 1x
cell A2: 3x
cell A3: 5x
cell A4: empty (empty cell, not text 'empty')
````
In cell A5, I want to output the 40 percentile of values in cells `A1:A4` without the `x` (ignoring empty cells), which will be 2.6 in this case, and add `x` to it. So the desired output of A5 is `2.6x`. In Google Sheets I can use
````
=concatenate(percentile(INDEX(REGEXREPLACE(FILTER(A1:A4,A1:A4<>0)&"","[^\d. ]",)+0),0.4),"x")
````
but not sure how to do it in Excel
