Formula to automatically consolidate list that's changing

[TinyDamooge]

Hi all,

Been trying to automate some data summary things I have to do.

I look for unique HAZXXX numbers, and show the unique DEXXX numbers next to them.

I've done all of it! - Except for the list I create has gaps in it.

Anyway to automatically remove the list gaps in the summary section of the attached spreadsheet?
Cheers!

An array formula in C3, copied across and down:

=IFERROR(INDEX(C:C,SMALL(IF(C$17:C$265<>0,ROW(C$17:C$265)),ROWS($1:1))),"")

Array Formulae are a little different from ordinary formulae in that they MUST be confirmed in the FIRST CELL ONLY by pressing CTRL+SHIFT+ENTER to activate the array, not just ENTER. After that, the array can be dragged down as normal, to cover the desired range.

You will know the array is active when you see curly brackets { } - or "curly braces" for those of you in the USA, or "flower brackets" for those of you in India - appear around the outside of your formula. If you do not use CTRL+SHIFT+ENTER you will (almost always) get an error message or an incorrect answer. Press F2 on that cell and try again.

Don't type the curly brackets yourself - it won't work...

or... an ordinary formula, coped across and down:

=IFERROR(INDEX(C:C,AGGREGATE(15,6,ROW(C$17:C$265)/(C$17:C$265<>0),ROWS($1:1))),"")

That works great thanks!

Cheers for removing the middle steps I'd been trying too!
