I made a tool to edit json files used in construct 2 array. This tool can be used as an windows application (with right click -> Open in windows explorer or right click open directly in construct 2).
To do that you must :
* Export it with NWjs plugin (and copy the version you want in your application directory for example Program files)
* open the capx with 7zip to export the EditArrayJsonNwjs.cmd (this file is in the \file\ directory inside the capx)
* copy this file in the directory you install you NWjs export
* associate the json extension to the EditArrayJsonNwjs.cmd
and... that's it
