FE13 Paragon question regarding importing DLC

[ZuccFE]

Hello! This is my first time posting in Serenes Forest Forums and also new to the FE Paragon Editor. I'm aware this is not a modding help forum but I saw some discussion around paragon editor ( but nothing about my particular question) so I figured I might as well try. So I’m trying to import the dlc for FE13 and have researched a little bit about how to do this but I’m quite confused. Apparently I need to turn the respective dlc files as app files, then into json files. I then need to use an old paragon version for importing said dlc json files. I’m not sure if I’m on the right track or not so if someone who knows paragon really well could help me out that would be great!
