==History and roadmap==
The name was originally an [[acronym]] for "Poor Obfuscation Implementation",<ref name="javaworld2004">{{citation |last1=Sundaram |first1=Elango |date=2004-03-22 |df=dmy |url=https://www.infoworld.com/article/2072333/excelling-in-excel-with-java.html |title=Excelling in Excel with Java |work=[[JavaWorld]] |access-date=2020-07-21}}</ref> referring humorously to the fact that the file formats seemed to be deliberately [[Obfuscated code|obfuscated]], but poorly, since they were successfully [[reverse engineering|reverse-engineered]]. This explanation – and those of the similar names for the various sub-projects – were removed from the official web pages in order to better market the tools to businesses who would not consider such humor appropriate. The original authors ([[Andrew C. Oliver]] and Marc Johnson) also noted the existence of the Hawaiian [[poi (food)|poi]] dish, made of mashed [[taro root]], which had similarly derogatory connotations.<ref>{{citation |url=http://www.coyotesong.com/poi/ |archive-url=https://web.archive.org/web/20041015142404/http://www.coyotesong.com/poi/ |archive-date=2004-10-15 |title=POI homepage from October 2004 |publisher=Coyote Song}}, showing original explanations for naming.</ref>

===Office Open XML support===
POI supports the ISO/IEC 29500:2008 [[Office Open XML]] file formats since version 3.5. A significant contribution for OOXML support came from Sourcesense,<ref>{{citation |url=https://www.sourcesense.com/ |title=SourceSense}}</ref> an [[Open-source software|open source]] company which was commissioned by [[Microsoft]] to develop this contribution.<ref>{{cite web
