To see how this works let’s do a short walkthrough of sample 6 that creates a report on a directory in the file system. 
The spreadsheet is created without any template. 
First sheet is a list of subdirectories and files, with an icon, name, size, and dates. The second sheet contains some statistics...

EPPlus also supports enumeration of cells....

 Heres an example how you can use EPPlus in a webapplication...

 Here's a few screenshots from the sample project...
