Formatting large excel documents in matlab

I need to format an excel file. Currently the formatting in the excel file is: Timestamp, Data1, Data2. In matlab i need to loop the timestamp in rows, and transform the Data 1 and Data 2 from columns to rows, while matching the time stamp.

Here is the excel file: https://www.dropbox.com/s/xy75z2xfma22hfz/Dataformat2.xlsx

I had a very large excel file, so to shorten it up, i cut down the column to 3 per data set( they are highlighted in green and blue)

Timestamp,Data1 TimeStamp,Data2
