I was going through my hard drives, and I saw this project I did a long time ago when I was in active development of Dekaron. Originally called "CSV Helper", now it's essentially a toolkit for server development. I ported it to .NET8, and releasing it here.
Some of it's features:
* Looking up drops
* Reverse search of drops to find which monsters drop said item
* Map viewer with filters for walkable space and monster spawns
* Server integrity checker
Link for download:

On first run, you'll be greeted with an error message about files not being found. Go to the settings tab and add the data and share folders, click save.
I'm not sure what the state of Dekaron development is, and I'm not even sure if this tool works for any recent servers. I tried it on what I think are A9 files, and it seems to work.
