Abstract

You need a rank function which returns a unique rank, even if duplicates occur? One possible approach:

You need to press ALT + F11, insert a new module and copy the program code below into the new module, then return to your spreadsheet, select cells A12:C15 and enter =sbUniqRank(A2:C5) with CTRL + SHIFT + ENTER as an array formula.

'Array function to rank a range with unique ranks.
'vCountFrom determines from where you count in case of duplicates:
'1 = first rows (1 to count), then columns (1 to count), i. e. top left to top right (tltr)
'2 = starting with top right to top left, then downwards (trtl)
'...
'8 = starting with bottom right to top right, then to the left (brtr)
'If bJustNumeric is True then Rank will be used to rank, if False then Countif will be used.
'lOrder is like Rank's order: 0 = Descending, 1 = Ascending
