I would like to convert an object ID name to a string (like AdventurerOrcWarrior01). Is this possible and if so, how would this be done? Thanks!

The only two things you can get an EditorID for are cells and quests (OBSE's GetEditorID will do those two) and you'd start from a numeric RefID to get there. I'm not sure if you can take a displayable name (e.g. "Adventurer" for your example) and get an ID from it at all, as there are so many synonyms involved. However, you can get the display name from a RefID with GetName, as seen in the FormID Finder and RefScope mods.

Just to clarify, I have an Object through GetBaseObject and want to put the name found under the Editor ID in a string. I did notice the cells and quests thing, but I need it for npcs. I was hoping there would be a way to compare the name to a certain string, as GetName doesn't give the right info.

nm... didn't click that you tried GetName...

In that case no. The EditorIds are otherwise converted to the numeric when the forms are compiled in the CS, and are no longer available in-game. The Cell name and Quest name are special cases, the first for supporting GetInCell, and the latter for console support.
