I need to calculate the MIN and MAX values for Transfer Start Time (F) and Transfer End Time(H)

and put data like below in same excel at Sheet1

System Name Start Date  Start Time  End Date    End Time    "Total Duration(HH:MM:SS)"
BR502V7C    25-09-2021  07:46:46    25-09-2021  21:16:04    13:29:18
BR111V11    24-09-2021  01:06:45    24-09-2021  07:55:49    06:49:04

What I have tried:

e.g. for 1 server

Start Time=MIN(Sheet2!F2:F6)
End Time=MAX(Sheet2!H2:H6)
Total Duration(HH:MM:SS)=E2-C2

Need help in how to do this

And what is wrong with the way you have done it?

I am not aware not to do excel calculations in powershell

As I already suggested: use Excel formulas, or write VBA macros.

If I was trying to find the minimum and maximum values of data in Excel I would just use a pivot table - either a straight forward pivot or a pivot query using Power Query.

In Excel it's probably best to combine the date and time into a single column (for calc purposes - it doesn't have to be permanent). You can then just subtract one datetime from the other - see How to Calculate Elapsed Time in Excel | Excelchat[^]

It's not clear where or why Powershell comes into this - but you may find this post useful By Example – PowerShell commands for Excel | SQL Notes From The Underground[^]
Powershell (or VBA) can also be used to auto-refresh the pivot data as necessary
