I'm trying to process an array formula in my template:
{=INDEKS(F2:H2;MATCH(A1;F2:H2;0))}
But jxls renders it as an ordinary formula?
=INDEKS(F2:H2;MATCH(A1;F2:H2;0))
Which doesn't work.
It seems Apache POI supports array formulas since 3.13 (the version I'm using with jxls)
No, as of jxls-2.3.0 it does not support array formulas.
You can raise an enhancement request at Jxls issue tracker to request it.
