In the modern construction field, many advanced software tools are available for structural design, but they are often complex and not easily accessible for all users. Microsoft Excel plays a major role in engineering calculations because it is simple, flexible, and capable of mapping data efficiently without errors. In this study, a spreadsheet-based tool is developed for the design of reinforced cement concrete (RCC) elements such as slab, beam, column, and footing. The design follows a load transfer path from slab to footing. The spreadsheet is created based on IS 456:2000 provisions, where only selected input cells are editable and all other cells are pre-formulated. The tool helps to determine whether the structure is safe or unsafe and provides reinforcement details. This method is useful for basic design understanding and preliminary structural verification.
