Using formulas in calculated columns in lists can help add to existing columns, such as calculating sales tax on a price. These can be combined to programatically validate data.
When entering formulas, unless otherwise specified, there are no spaces between keywords and operators. The following is not an exhaustive list. To view all formulas, see the alphabetical list at the end of this article.
Note: Calculated fields can only operate on their own row, so you can't reference a value in another row, or columns contained in another list or library. Lookup fields are not supported in a formula, and the ID of newly inserted row can't be used as the ID doesn't exist when the formula is processed.
Conditional formulas
You can use the following formulas to test the condition of a statement and return a Yes or No value, to test an alternate value such as OK or Not OK, or to return a blank or dash to represent a null value.
