Json inspector

Json inspector is a simple tool originally meant to explore my game’s JSON save files.

This version is a more polished rewrite in Python 3.13+ and Qt6. It’s built for performance—save games can be ~100 MB of JSON—so parsing and UI tasks run in background threads.

Download

Binary

Please download the latest installer/binary for your os.

• .msi for Windows
• .deb for Ubuntu/Debian

Python

For windows substitute python3 for python. As python3 just leads to their store to download some version of it.

git clone https://git.scarlettbytes.nl/scarlett/json-inspector.git 
cd json-inspector
pip3 install -r requirements.txt
python3 run.py [/dir/to/file.json[.gz]]

How to run

Binary

After installing you should be able to run it via the GUI of your OS by searching for json inspector. It will also register (on linux at-least) the json-inspector command which also opens the application and takes a path to a file to open with.

Python

• With a file argument

python run.py /path/to/file.json[.gz]

• Without arguments

python run.py

Opens a file selector dialog.

File association

To integrate with your OS, go to Settings > Settings… > Associate JSON files with this app. This will register .json and not .json.gz files to open automatically in the app.

Requirements

It uses little resources except when loading, writing and searching, for hardware the following should be sufficient:

• 1-2gb dedicated ram (~100mb json file)
• Quad core processor (to keep it responsive).

These requirements are only needed if you are running the script directly as python:

Runtime

• Qt6
• orjson (optional; falls back to stdlib json)
• gzip support (builtin)
• psutil

Build (if running from source)

• Python 3.13+
• PyQt6

How to build

To build locally on linux for a deb file, you can just use docker compose up. It should build inside the container and exit after being build.
