I am trying to use Spreadsheet gem to import some data in the db. I open
a xls as
but after that when I try to open the file using Excel I get an error
that file is locked by another user for editing. Only way to release the
lock is to kill the rails server. And there is no method to close the
file in the gem. How do I solve this problem? 'Roo' also had the same
issue. Is there any gem which I can use to import/export the data from
excel which does not have these issues?
