Excel = actxserver('Excel.Application');
%%
fullPathToExcelFile = 'C:\Users\User1\Desktop\ExcelToMatlab_COM\rtd1.xlsx'; % Please modify this to the location of your excel file
ExcelWorkbook = Excel.workbooks.Open(fullPathToExcelFile,0,true);
WorkSheets = Excel.sheets;
Excel.Visible = true;                     %make excel visible so user can interact
%%
TargetSheet = get(WorkSheets,'item','Sheet1');
Activate(TargetSheet);
%%
DataRange = TargetSheet.UsedRange;
r = DataRange.Address;
data = DataRange.Value;

registerevent(TargetSheet, {'Change',@(TargetSheet) @ExlData});

function t = ExlData(TargetSheet)
%     data = range.Value
    temp = TargetSheet.UsedRange;
