Application data sheet

[lordface]

Hello,
Wondering if anyone can help me with this datasheet I've been given, It asks to convert 1 minute data to 5 and then 15 minute data.
This may sound stupid but am to take the average of those 5 minutes or the sum for the conversion?
Also if anyone has any idea on how to answer that as its given in 3 columns - date,time and Irradiance values any suggestions for the code would be greatly appreciated.

Welcome to the forum!

Will you please attach a sample Excel workbook? We are not able to work with or manipulate a picture of one and nobody wants to have to recreate your data from scratch.

1. Make sure that your sample data are REPRESENTATIVE of your real data. The use of unrepresentative data is very frustrating and can lead to long delays in reaching a solution.

2. Make sure that your desired results are also shown (mock up the results manually).

3. Make sure that all confidential data is removed or replaced with dummy data first (e.g. names, addresses, E-mails, etc.).

4. Try to avoid using merged cells as they cause lots of problems.

Unfortunately the attachment icon doesn't work at the moment, so to attach an Excel file you have to do the following: just before posting, scroll down to Go Advanced and then scroll down to Manage Attachments. Now follow the instructions at the top of that screen.

Please pay particular attention to point 2 (above): without an idea of your intended outcomes, it is often very difficult to offer appropriate advice.

Hi lordface and welcome.

It might help if we can see the file.

Click on GO ADVANCED and then scroll down to Manage Attachments to open the upload window.
Select the file, click 'upload file' then 'close this window' to attach it.

I should of attached the file now with how I imagine the solutions to look.
I have shown how to answer so its the sum of the 5 minutes, but I could be wrong in my approach.

If you combine date and time in a single column,

	A	B	C	D	E	F	G
1				Interval	0:15:00		D1: Input
2	Date/Time	Irradiance		Date/Time	Irradiance
3	12/01/2017 07:03	0.00		12/01/2017 07:00	0.00		D3: =FLOOR(A3, $E$1)
4	12/01/2017 07:04	0.00		12/01/2017 07:15	0.00		D4: =MROUND(D3 + $E$1, "0:00:01")
5	12/01/2017 07:05	0.00		12/01/2017 07:30	0.00		E3: =AVERAGEIFS($B$3:$B$767, $A$3:$A$767, ">=" & D3, $A$3:$A$767, "<" & D3 + $E$1)
6	12/01/2017 07:06	0.00		12/01/2017 07:45	0.08
7	12/01/2017 07:07	0.00		12/01/2017 08:00	16.92
8	12/01/2017 07:08	0.00		12/01/2017 08:15	85.08
9	12/01/2017 07:09	0.00		12/01/2017 08:30	148.58
10	12/01/2017 07:10	0.00		12/01/2017 08:45	225.17

Thanks shg,
That great although my data isn't continuous for the time values i.e not a full 24 hours and each day might have a slightly different length for the data recorded, so how can I alter the macro so it knows when to start a new day?

[shg]

There is no macro, just a formula, and I don't understand what change you need.
