The answer depends in part on how the data is formatted in Excel, but something like this should get you started (see attached spreadsheet):
tbl = readtable('Peaks.xlsx');
contour(tbl.Variables,0.1:0.1:1);

If you replace Peaks.xlsx with Sai.xlsx, my example code seems to work fine on your data.
tbl = readtable('Sai.xlsx');
contour(tbl.Variables,0.1:0.1:1);
If you ran into some issue with that code, could you give more detail? For example, what error messages did you get? Did the picture not look like you expected?
