Is there a guide on how to use custom formats for cells in apache poi?
I have a vague idea on how basic formats work such as $#,##0.00 producing outputs like $1,000.00 as described here.
However upon looking at this example I saw something this: wb.createDataFormat().getFormat("_($* #,##0.00_);_($* (#,##0.00);_($* \"-\"??_);_(@_)")
which I cant make heads or tails of.
as stated by @Gagravarr above, these are not poi specific. this link should help anyone else having problems with this
