How can I implement a clean dialogue tree without spaghetti code in a 2D RPG?

I’ve been trying to implement a basic dialogue system for my 2D RPG, but I’m stuck on how to structure the branching logic cleanly without it turning into spaghetti code. My current approach uses a ton of nested if-else statements and it’s already becoming unmanageable with just a few conversation paths.

I remember banging my head on this when I added a second NPC. I ended up building a small graph of nodes and edges, not code in nested ifs, and kept a separate data file for lines and branching. It still felt fragile, but it was easier to tweak than reworking a forest of ifs.

One approach I tried was data driven dialogue where each node has speaker, text, and a list of choices that point to other nodes. The code kept a tiny runner that follows the chosen edge. It let me add branches without touching the code, but it required a tooling habit and validation to avoid orphan nodes.

Do you feel like the real bottleneck is the branching itself or the way you validate which branches are allowed based on game state?

I used a basic state stack to avoid deep nesting: push a topic node, pop back when it's done. It wasn't perfect, but it kept me from chasing the spaghetti. Also I limited to about three or four choices per node so the editor doesn't explode.
