I have an excel file of time and want to convert the time values to datevec format. The format of time in excel file is like '1/17/2018 16:20:37', '1/17/2018 16:25:37' and so on. I want these values in this format: year, month, date, hour, minutes and seconds. Also, when I read the xlsx file in MATLAB, it automatically converts time to 12 h format like 4:20:37 pm. Please help.

I'm gonna suggest that you likely don't need to do this. Unless you are using a pretty old version of MATLAB, use datetime instead of datenum/datevec/datestr.
If you want, for example, the hour field, it's simple to get it from a datetime when you need it:
>> t = datetime({'1/17/2018 16:20:37', '1/17/2018 16:25:37'})
t =
1×2 datetime array
17-Jan-2018 16:20:37 17-Jan-2018 16:25:37
>> t.Hour
ans =
16 16
Also, you should probably be using readtable to get the timestamps and whatever else is in the spreadsheet into MATLAB. It will make life much easier.
