A tool that allows you to export parts of the content tree into Excel and then after make changes, import those changes back into Sitecore.
This was a solution we created for the 2017 Sitecore Hackathon. The team We do it for the Cookies consisted of Leo Bevelacqua, Rob Mcclanahan and Dylan Young.
This solution is in alpha, if you run into any issues please report them in the issues section.
