I use excel sheets for the design of structural elements such as beams, slabs, columns, footings, brackets, shear walls, retaining wall, water tanks etc. These excel sheets are prepared by me under the provisions of ACI code. The results from these sheets are in good agreement with the results of software, hence proving my understanding of reinforced concrete design philosophy and application of ACI code, further testifying my command our the use of Microsoft Excel.
