How do I read (hours) data from the .xlsx file?

2 views (last 30 days)
Hello,
I have the following issue. In a .xlsx file I have in column D hours (format: 00: 00: 00,01: 00: 00, ... 23:00:00). How can I integrate (read) them into the code to use them to plot some graphics I want. Your help is important.

[~,~,ALL_Data]=xlsread('Hours_Data.xlsx');
Hours = days(cell2mat(ALL_Data(2:25,end)));
Hours.Format = 'hh:mm';
Hours
Hours = 24×1 duration array
00:00 01:00 02:00 03:00 04:00 05:00 06:00 07:00 08:00 09:00 10:00 11:00 12:00 13:00 14:00 15:00 16:00 17:00 18:00 19:00 20:00 21:00 22:00 23:00
%OR
ALL_Data = readtable('Hours_Data.xlsx');
Hours = days(ALL_Data{:,end});
Hours.Format = 'hh:mm';
Hours
Hours = 24×1 duration array
00:00 01:00 02:00 03:00 04:00 05:00 06:00 07:00 08:00 09:00 10:00 11:00 12:00 13:00 14:00 15:00 16:00 17:00 18:00 19:00 20:00 21:00 22:00 23:00

Read about readtable. In here after reading your specify the format of time. Have a look on duration.

If the answer is NO, that you have technical problems or legal restrictions that prevent you from uploading a small sample file, then just say so, and we will provide additional steps to figure out exactly what is happening. But if you were hoping for an answer soon and there is no technical or legal restriction to uploading a small sample file then upload a small sample file
We. Need. To. See. Exactly. What. Is. Stored. In. The. File.
Not what an image of it looks like. Excel permits many different kinds of data to be displayed as the same thing.
