I am using EPPlus open source tool for creating / editing excel files on server. When I insert data to excel created by EPPlus by opening it using C# .net code some time size of files gets increase upto 8-10Mb. If I copy all content in MS Excel from that file and save it then it is of only 20 kb.
What should be the actual cause behind increasing excel file size created by EPPlus
It was due to unreadable content generated in excel it self. When I used new release of EPPlus (4.1.0) I have not get any problem like this.
