Updating Excel Template

I don’t know of any that will this exactly (i’m unsure as to even how feasible it is), though the closest I’ve found is the Export JSON to Excel plug-in (which i favor for certain things for various reasons including its ability to essentially use an arbitrary dictionary as input instead of having to dedicate a whole CDT to it, or to use the Export DSE to Excel smart service and suffer any of its pretty-severe deficiencies...)
