--- Comment #2 from PJ Fanning <fannin...@yahoo.com> --- POI is a volunteer project. The small number of volunteers tend not to take too much interest in issues where users have large files but have constrained memory. Memory is cheap, developer time is expensive. There are config options to get POI to use temp files. They might help in this case. https://poi.apache.org/components/configuration.html There are APIs in POI for reading xlsx files in a streaming way. * https://poi.apache.org/components/spreadsheet/how-to.html#xssf_sax_api * https://github.com/pjfanning/excel-streaming-reader If you want to work on a patch for POI yourself, feel free to create a PR. -- 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
