Subject [Bug 61371] 20^20 hidden cells in a .xlsx file causes heap memory full exception
Date Wed, 02 Aug 2017 18:42:40 GMT

--- Comment #3 from PJ Fanning <fanningpj@yahoo.com> ---
The XSSF model loads all the data in the xlsx file, even if it is hidden, The
XSSF cell interface will let you know which cells are hidden and which are not.
In theory, the XSSF workbook code where we load the xlsx data could have an
option to ignore hidden cells or hidden sheets. This would be an enhancement
and I'm not sure how useful this feature is.
You could also try the XSSFReader which let's you read the xlsx file in a
streaming way.
