JChem for Excel Reactor
There are two functions in JChem for Excel that generate products from reactants according to a reaction schema:
JCReactProductStructure function constructs a possible product for each reactant pair, i.e., the result of this function is one product per cell; and
JCReactReactionStructure function constructs a possible reaction for each reactant pair, i.e., the result of this function is a reaction equation in a cell.
