Hi…

require “spreadsheet/Excel”

in my controller i have a method to generate reports for my logs.  
That functionality works fine.  
Why do i get the below errors in my server console.

[DEPRECATED] By requiring ‘spreadsheet/excel’ you are loading a  
Compatibility  
layer which provides a drop-in replacement for  
Spreadsheet::Excel  
versions \<= 0.3.5.1. This code will be removed in  
Spreadsheet  
version 1.0.0

Thanks for any help!

This is answered on the guide on the gem’s homepage. (Too be far, the  
“have a look at the GUIDE” link is broken, but just scroll down a tiny  
bit…)
