Hello,
I want to import an excel sheet and convert it into a time table. Currently the dates are in serial excel format.
From what I understand table2timetable only accepts dates in string or vector format. How do I convert the format of a entire column to date string?
tbl = readtable('data.xlsx');
%convert first row of table to string date
TT = table2timetable(tbl)
Some example data from the read table:
Date Data1 Data2
_____ _________________ ________________
43373.53 275.54 43.516
43373.54 292 43.639
43373.55 215.67 43.443
Thanks!

Wlter's answer is correct, but it's worth noting that in recent versions of MATLAB, assuming the data are stored appropriately in the spreadsheet, readtable will create those datetimes automatically. And in slightly earlier versions, you can tell readtable to create datetimes. It is possible, however, for the data in the spreadsheet to be stored in a way that foils readtable.

TT = table2timetable(tbl(:,2:end), 'RowTimes', datetime(tbl{:,1}, 'convertfrom', 'excel'));
