A generic tag for questions concerning spreadsheet formulas. Use only when there is no more specific tag, such as [excel-formula] or [lotus-formula].
In a spreadsheet, formulas allow users to populate spreadsheet cells with data calculated by some mathematical, statistical, lookup or text-manipulating formula, often using references to the values of other cells. Formulas will automatically be re-evaulated when a referenced cell changes, allowing users to see how changes in inputs affect the value of the formula. This also creates the possibility of feeding more complex input into other formulas or charts (by referencing one or more cells whose values are set by formulas).
