Description
OpenFormula is an open format for exchanging recalculated formulas between office application implementations, particularly for spreadsheets. OpenFormula defines the types, syntax, and semantics for calculated formulas, including many predefined functions and operations, so that formulas can be exchanged between applications and produce substantively equal outputs when recalculated with equal inputs. Both closed and open source software can implement OpenFormula.
OpenFormula is intended to be a supporting document to the Open Document Format for Office Applications (OpenDocument) format, particularly for defining its attributes table:formula and text:formula. It can be used in other circumstances where a simple, easy-to-read infix notation is desired for exchanging recalculated formulas.
