  • Hello! welcome to Sopt. To import an excel file you can use the function xlsread.

Recommend:

  1. use the xlsread command,
  2. or convert the file to csv format and then use the csvread command,
  3. or if none of these solutions please you you can use the readtable.

For the latter, I will show how to import an excel file containing dates to a table in Matlab. Be the hypothetical.xls weight file with the following data.

   Data        Peso
___________    ______

31-Oct-1996    174.8 
29-Nov-1996    179.3 
30-Dec-1996    190.4 
31-Jan-1997    185.7

Now do the following.

T = readtable('weight.xls')

T = 

    Data        Peso
____________    ______

'10/31/1996'    174.8 
'11/29/1996'    179.3 
'12/30/1996'    190.4 
'1/31/1997'     185.7

In windows, with Excel, the Data variable is a string field of the Cell array. To convert it just do:

T.Data = datetime(T.Data,'Inputformat','MM/dd/yyyy')

T = 

   Data        Peso
___________    ______

31-Oct-1996    174.8 
29-Nov-1996    179.3 
30-Dec-1996    190.4 
31-Jan-1997    185.7
