Hi!

I know I can dig deeper into a nested JSON object by adding new elements to a path.

For example if I have an array of objects called NPCs then I can add ."my1NPC" to change the path to NPCs.my1NPC and then ".health" to change the path to NPCs.my1NPC.health and so on.

But is there a way of moving back up in the chain? If the JSON.path is currently set to NPCs.my1NPC.health then how can I back it down back to just NPCs.my1NPC (for example)?

Usually you do this using nested For Each Element loops.
+ JSON: For each entry in "NPCs" ----+ JSON: For each entry in "."

You can also always use an absolute path instead of a relative path.

Or maybe you're looking for the 'set path' action?

Thank you for your answers!

dop2000 That is a brilliant function, will definitely keep that one around for reference.
In my situation, I ended up solving the need of "backing down" or "traversing up" the hierarchy by storing the paths at various points into variables and loading the required nesting level from those.
