To create a formula in a cell, use the CellRange.Formula property of the Cell object. Assign the required formula to this property as a string starting with the equals sign (“=”).

This example demonstrates how to create a simple formula using constants and calculation operators, and add this formula to a cell. Constants are values that are not calculated (e.g., date values, numbers, text strings). Operators specify what calculations should be performed on a formula’s elements.
