An open-source JSON Editor for manipulating JSON files in text and tree views.



Getting started


The precompiled executable is available for download on the github repo

Python Install

If you choose to run the interpreted code through python, you can pull the source code from the github repo, install module requirements (PyQt5, Qscintilla, QtAwesome, and Pyperclip) by changing to the source folder and running:

pip3 install -r requirements.txt

Once the requirements are installed, you can run JSONitor through Python 3 from the source folder.


The application window should appear.
