Is the data in excel file only corresponds to colormap or the background image too?

try this
data = readmatrix('data.xlsx');
lat = data(:,1);
lon = data(:,2);
val = data(:,3);
latV = linspace(min(lat), max(lat), 100);
lonV = linspace(min(lon), max(lon), 100);
[latG, lonG] = meshgrid(latV, lonV);
valG = griddata(lat, lon, val, latG, lonG);
contourf(latG, lonG, valG, 100, 'LineColor', 'none')
colormap(jet)
colorbar
