I am trying to post-process data that can be found in a .xlsm file. First, I am trying to successfully export the data into MATLAB. I am not receiveng any error messages, the issue is that the output is not the specified range I am asking for. I tried using readtable, readmatrix, xlsread: they all have the same issue. I also tried the import tool, but that was also unsuccessful. I suspect the issue is that some cells are empty so that is somehow cofusing the command I am calling to import a range of the .xlsm file I am using. For reference, the range I am asking for is A147:RS1057. When I go back to double check the table MATLAB gives me with that actual range in the excel file, it is not the same. Any help would be appreicated, thank you!
