Hello!
Ok I am in need of some help here. I am reviewing timesheets and looking for any overlapping punched in time slots.

Example:

Excel Facts

When did Power Query debut in Excel?
Although it was an add-in in Excel 2010 & Excel 2013, Power Query became a part of Excel in 2016, in Data, Get & Transform Data.

Hello!
Per SanjayGMusafir request:
Office Version 365
Platform Windows
Microsoft® Excel® for Microsoft 365 MSO (Version 2311)

The times that are provided are manually entered in by employees. I need to perform a weekly audit to ensure that there are no overlaps. There are times where there may be multiple entries that overlap. Everything provided are examples that we consistently run into.
Assistance on streamlining this process would be greatly appreciated.

I am unable to upload the Excel document as my work computer is not allowing me to download the XL2BB file.

I adjusted sorting the times if this makes it easier to understand:

NameDateStart TimeEnd TimeOverlap

Check this and revert -

please note as under -
  1. It is suggested to convert your data to a Formatted Table. It shall help you over a longer period
  2. The Data needs to be sorted in Order - Name, date, Start time, End time for formula to work properly.
  3. Your sample data has few wrong overlaps marked that my formula has eliminated. Please check for the accuracy of formula for that purpose.

This does not work with what I am trying to achieve

I have marked what is considered an overlap in time and what is not. I am looking to utilize a formula that will inform me if there are multiple overlaps in time punches and inform me if there is an overlap.

Just change formula as below -

Excel Formula: 
=IFS(AND(A3=A2,(B3+C3/24)=(B2+C2/24),(B3+D3/24)=(B2+D2/24)),"Overlap",AND(A3=A2,(B3+C3/24)<=(B2+D2/24),(B3+C3/24)<(B2+D2/24)),"Overlap",TRUE,"No")

Unfortunately the provided formula does not work for what I am trying to achieve

Time Slot (Start Time to End Time)
#1 Time Slot - Overlaps #2 & #3
#4 Time Slot - Overlaps #2

Time Slot entries such as #1-#4 are common and will need to be found

Unless you share your actual data using XL2BB, I can't help any further. I have no way to find where and how things are going wrong.
