I have spreadsheets with file extension of ´'xls' which were generated by LABVIEW (not EXCEL). Those files can be read in EXCEL.
I tried to use "readtable" "readmatrix" "readcell" or "xlsread" to read those files in matlab. none of them work.
"Unable to open file as a workbook. Check that the file exists, read access is available, and the file is a valid spreadsheet file."
The problem can be solved by using EXCEL to open and save the file as .xls or xlsx file (exactly as the original file name) .
But I am worndering if there is an easy solution in MATLAB.
Thank you very much.
