Display a name from a cell range, round-robin

Another day, another Google Sheets (Excel-like) challenge.  :)

This time, I have a column of team names. The team names may or may not have an entry code associated with their team.

I spent nearly 2 hours searching the internet for answers. It seems that no one has tried to do this with just formulas. I found a few examples, but they required scripting. :(

The challenge is that I wish to automatically assign a reviewer (from Reviewer List column) if the team has an entry code. But in doing so, I want to assign a reviewer round-robin style, so that each reviewer is assigned approximately an equal number of teams.

Please see example sheet:

The way I am currently doing this isn't very smart, names are not used sequentially (and round-robin), every time there is a value in the Shared Entry column. What I wish to see is what is shown in the Expected Results column.

But to accomplish this challenge, it will need to work in Google Sheets, use only formulas, and work without add-ons.

Is this even possible?

Thank you so much

Are you willing to list your reviewers in reverse order? If so, put the following formula in cell F2 and copy it down:

Without need to reverse the order of reviewers, I put this formula in cell E2 and copied down:

Hello byundt,

Thank you again for that elegant formula. :)

I am trying to decypher the formula to try to understand it a bit better. Can you explain it a bit?

I would like to make a minor modification so that instead of being triggered by any value in the Shared Entry column, only values beginning with ASC will trigger a name.

I originally thought that I could just change,
=if($C4="ASC*","", but clearly I am not understanding how this works. :(

Thank you. :)

I don't believe the IF function takes wildcard characters like *. It doesn't in Excel.

In Excel, you may use wildcard characters in COUNTIF, COUNTIFS, SUMIF, SUMIFS, AVERAGEIF, AVERAGEIFS, MAXIFS, MINIFS, HLOOKUP, MATCH, VLOOKUP. I haven't tested whether the equivalent functions in Google Sheets may use wildcard characters, but think it likely.

You should be able to use =IF(LEFT($C4,3)<>"ASC","", balance of formula)
