An RTON file is a data file used by Plants vs. Zombies 2 (PvZ2), an Android and iOS game where you try to fend off zombies with plants. It contains binary game data about plants, zombies, assets, levels, and other game elements.

RTON files may be stored in the "CDN" game assets folder in the PvZ2 installation directory. You can edit the RTON file by converting it to a .JSON file using rton2json, which is included with the TileTurnip's Tools download. You can then edit the JSON file with a text editor. After editing the file you can convert it back to a JSON file using json2rton, which is also included with TileTurnip's Tools. RTON files may also be stored in .OBB files. In order to view or edit an RTON file stored in an OBB file, you must first extract the RTON file from the OBB file using Quickbms. Then, you can convert it to a JSON file using rton2json, view or edit it with a text editor, then convert it back to a JSON file using json2rton.
