Named function
A named function is a custom formula you define once and call by a friendly name in any cell. Google Sheets uses LAMBDA under the hood via Data > Named functions. Instead of repeating a long expression, you write =DISCOUNT(price, rate) everywhere. Named functions make templates readable and reduce copy-paste errors across tabs.
Read guide →LAMBDA
LAMBDA defines an anonymous function inside a formula. You name parameters, write the calculation, then pass arguments when you call it. Combined with MAP, BYROW, or a named LAMBDA in the Name manager, it replaces fragile copy-paste logic across big tables.
Read guide →Google Sheets formulas
A formula is an instruction in a cell that calculates a result from other cells, ranges, or built-in functions. Every formula begins with =. When inputs change, the sheet recalculates so dashboards and models stay live without manual copy-paste. Formulas are the default automation layer inside the grid before Apps Script or add-ons.
