As far as I understand, the Formula Evaluator was added for the
use-cases where a POI user wants to calculate the value of a formula in
a cell within his Java program. The ability to parse and evaluate a
formula is not required to simply write out excel files through POI.
I haven't seen the internals but I guess the Ptgs you see within the
cell object must have been generated by the Formular Parser. I think
these Ptgs will not participate in generating actual excel file and are
for use with Formula Evaluator only.

Hi,
I was just wondering about the formula evaluation algorithm. Why do you need
the FormulaParser at all. The cell already contains the Ptgs within the
formula record. But you transform the Ptgs into a string representation and
then parse the string to reconstruct the Ptgs.
Maybe I miss something, but I really don't see the point.
Thx,
Günter
