--- Comment #12 from Javen O'Neal <one...@apache.org> --- You might also try looking at CellUtil, which will look through existing CellStyles and create a new CellStyle only if one that matches your desired style exists. This is basically the same as what your HashMap is doing, but with code maintained by POI. If this class doesn't support data formats, send a pull request or patch. https://poi.apache.org/apidocs/org/apache/poi/ss/util/CellUtil.html -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@poi.apache.org For additional commands, e-mail: dev-h...@poi.apache.org
