Java Excel parsing tool EasyExcel
Java parsing, Excel generation frameworks are well known Apache POI, JXL. Poi has a SET of SAX mode API, which can solve some problems of memory overflow to a certain extent. However, POI still has some defects. For example, the decompression and storage after decompression of 07 Version Excel are completed in memory, which still consumes a lot of memory. Easyexcel rewrites poI for 07 version of Excel parsing, can originally a 3M Excel with POI SAX still needs about 100M memory reduced to KB level, and then the large Excel will not overflow memory, Version 03 relies on POI’s SAX schema. The model transformation is encapsulated in the upper layer to make the user more simple and convenient.
