Check for overlapping dates by userID

[nathangwynmorris]

Hi All,

Been scratching my head on this for a while... I have a spreadsheet with the following:-

Column A = UserID [this varies on the number of entries based on the number of requests]
Column B = StartDate
Column C = EndDate

What I am trying to do is group up on the userID and then check column B and C to see if any of the dates above or below for that user overlap? So ideally in D2 would be my first formula. Ideally the data doesn't need to be sorted by ID or start date. And perhaps I could just have a simple overlap when the dates overlap and OK if there is no overlap

Any help would be amazing!!

Try this table based solution.

Formula in range D2:D7 :

=IF(SUMPRODUCT(([@StartDate]<FILTER([EndDate],[UserID]=[@UserID]))*([@EndDate]>FILTER([StartDate],[UserID]=[@UserID])))>1,"Overlap","OK")

I could not get XL2BB to work.

As the OP is using 2013 he/she doesn't have the Filter function.

Hey @Fluff, that's correct - thanks for trying though @Herakles. The only other thing I can do is use Google Sheets if the filter function is available there? I tried the above formula and it doesn't seem to work but maybe needs to be tweaked. I have checked the forum too - and nothing is shouting out at me as an obvious answer
