xls write data read with set of signals from xls

I would like to read specific data from xls sheet after the xls write operation from m script.

As per the snip, XLS write data is done for set of signals in the xls sheet and i would like to read the same data .I have tried with xlsread(filename, sheet,range)

But getting error "Range argument must be a string. See HELP XLSREAD"

data=xlsread(testFile,tabName,Column_expected);

'Column_expected 'range will change "for i = 1:length(outputSignalNames)"

as per the Test plan Image , i would like to read the data in specific cell with respect to signal names.

Please suggest for any example
