POI Fast Calc ====================== [![Travis-CI Build Status](https://api.travis-ci.org/moparisthebest/poi.svg?branch=master)](https://travis-ci.org/moparisthebest/poi) A Java library to calculate Excel formulas quickly. This is a fork of [Apache POI](https://poi.apache.org/) version [3.16](https://github.com/apache/poi/tree/REL_3_16_FINAL) that serves simply to calculate formulas quickly, it supports XLSX (Excel 2007) row/column limits in the HSSF engine for much faster evaluation than XML-backed XSSF is capable of, with the drawback that it can't read or write XLS/XLSX files from or to disk. Read the [email thread](https://lists.apache.org/thread.html/0bc90a3ed386edddfcb9b93ce6c262ad145a6b0433d0fcfe70ef10a2@%3Cdev.poi.apache.org%3E) with my original proposed patch to upstream poi for background. To use, add this to your maven pom.xml: ```xml com.moparisthebest.poi poi-fast-calc 3.16-SNAPSHOT ``` The `org.apache.poi` package has been renamed `com.moparisthebest.poi` and all dependencies removed, so this can cleanly live aside modern/newer upstream poi forever, and shouldn't ever need to change.
