JSON is everywhere in games — config files, save data, level metadata, animation definitions, you name it. The JSON Editor opens any JSON file as an editable tree, with type-aware controls per node, a search box, and a Monaco escape hatch when you really do want to edit the raw text.

It's the difference between "scrolling through a 600-line file" and "click the field, change it, save."

Features

  • Tree view. Every object, array, and value rendered as a navigable tree. Expand and collapse branches; jump to any node instantly.
  • Type-aware inline edits. Numbers get number inputs, booleans get toggles, strings get text inputs, null and undefined get the obvious controls. No more accidentally turning 42 into "42" because you mistyped.
  • Node inspector. Click any node and see its path, its type, and edit its value in a focused panel.
  • Search. Find any key or value anywhere in the document. Useful for big config files.
  • Monaco escape hatch. When you want the raw text — paste a chunk, do a regex find-replace, or just see what's actually on disk — switch modes and you're in a full Monaco editor.
  • Validates as you edit. Catches malformed JSON before you save and break your game.
  • Save to the VFS. Saves track version history, so a bad edit is one revert away from being a non-issue.
  • Multiple windows. Compare two config files side by side, or edit several at once.

What you walk away with

  • Cleanly edited JSON, with no syntax mistakes.
  • A way faster path through "I just want to change this one number" than opening it in a text editor.
  • Version-tracked files you can roll back if a save goes sideways.

JSON editing isn't glamorous. This tool makes it bearable — and most of the time, that's all you need.
