How does your team use Excel as a quote tool?

Some departments still rely on their macro heavy excel tools that "does it all"....Price, quote, send for approval, capture data. Other companies invest in a CPQ system that takes care of all the complexities...do people have use cases where they mix the two? 

All the 365 enhancements have made Excel a true collaborative tool, however I am wondering if there are best practices/examples on how to use Excel as a price-to-quote tool? 

I see connectors for Salesforce that can be purchased, that will effectively tie your Excel quote to the Salesforce proposal quote. 

I value the automation, but am curious if this is common for teams that rely on Excel as their main tool.
