Format the xls in this format

 

X,Y,Z,Attrib1,Attrib2 ..........

 

and save in csv format. Attrib1, attrib 2 will be the attribute of your data.

 

Now open ArcMap and add the csv. right click on the csv layer and click on "Display XY Data" ----------------

Now select the X,Y and Z source of your data. and set the projection system...............

Click ok a new layer should created. Now right click on the newly created layer sand export it as shape file. (if necessary edit it first)...

 

Now create tin from point layer and then create contour from it.....
