Importing large Excel docs into Jira for product requirements

[bcselewski]

We have a project we are working on, figured I'd reach out to the community.  We have a team that has a couple very large excel docs with multiple sheets.  Some contain data, some contain images. 

One sheet has almost 3000 rows and 4 sheets.  Does anyone have any experience doing something like this and if you did, do you have any tips we can give the team? 

Currently they are looking at a very manual approach and it's going to be an extensively long process.
