CodeInjection Download
Windows Developer Utility

Inject code from your clipboard
straight into your files.

Code Injection is a tiny always-on-top overlay for Windows. Copy a block of code, hold Shift, and it lands in your target file — then run it, open a console, or build a single EXE without leaving the panel.

What it does
INJ
Shift + Copy
Clipboard Injection
Hold Shift while you copy and the clipboard is written into the active target file in place. A timestamped backup is saved before every write.
PY
Drag & Drop
Auto TXT → PY
Drop any .txt or .py file onto the panel to set it as the target. Text files convert to .py automatically, picking a free name if one is taken.
EXE
One Click
Build to EXE
Compile the target into a single executable with PyInstaller from one button. If an icon.ico sits next to your file, it is used automatically.
RUN
Run / CMD
Instant Run
Launch the target with its default program, or open it in a console to watch the output — without switching windows or hunting for the file.
TOP
Overlay
Floating Panel
A frameless, stay-on-top window that follows you across apps. Hide it with F4, fade it to a ghost when your mouse leaves, and drag it anywhere.
BAK
Safe
Backups & Restore
Every injection keeps the previous version as a .txt backup. Roll back to it instantly from the panel if a paste did not go the way you wanted.
Get started
1
Install Python 3
Download and install Python 3 for Windows. During setup, tick Add Python to PATH. Tkinter ships with Python, so the interface needs nothing extra.
2
Install the required packages
Open Command Prompt (type cmd in the Start menu and press Enter), then run the command below to install tkinterdnd2 (drag & drop), keyboard (hotkeys), and PyInstaller (the Build button).
pip install tkinterdnd2 keyboard pyinstaller
Note: the keyboard package listens for global hotkeys such as F4, which on some systems requires running the terminal as Administrator.
