GUI Automation Tool (Form Filler)
This guide demonstrates how to create a script to automate repetitive GUI tasks using pyautogui. The example below is a "Bulk Data Entry" bot that types data into a form automatically.
Modules Used:
- pyautogui: For controlling the mouse and keyboard.
time: To handle delays.
Installation
pip install pyautoguiThe Code
Save this as form_filler.py.
import pyautogui
import time
def auto_fill(data):
# Safety feature: Drag mouse to any corner to stop the script
pyautogui.FAILSAFE = True
print("Please open your form/application.")
print("Move your mouse over the first input field.")
print("Script starting in 5 seconds...")
# Countdown
for i in range(5, 0, -1):
print(f"{i}...", end=" ", flush=True)
time.sleep(1)
print("\nStarting!")
# Click to focus the first field at current mouse position
pyautogui.click()
for person in data:
print(f"Entering data for: {person['name']}")
# Type Name
pyautogui.write(person['name'], interval=0.1)
pyautogui.press('tab')
# Type Email
pyautogui.write(person['email'], interval=0.1)
pyautogui.press('tab')
# Type Message
pyautogui.write(person['message'], interval=0.1)
pyautogui.press('tab')
# Simulate submitting (e.g., pressing Enter)
pyautogui.press('enter')
# Wait for next entry to load
time.sleep(2)
if __name__ == "__main__":
# Dummy data
users = [
{"name": "Alice Smith", "email": "alice@example.com", "message": "Hello World"},
{"name": "Bob Jones", "email": "bob@example.com", "message": "Automated entry"},
{"name": "Charlie Day", "email": "charlie@example.com", "message": "PyAutoGUI is fun"}
]
try:
auto_fill(users)
print("Done!")
except pyautogui.FailSafeException:
print("\nFail-safe triggered from mouse corner. Script stopped.")
except KeyboardInterrupt:
print("\nScript interrupted.")Usage
- Open a text editor or a web form (e.g., a Google Form with Name, Email, Message fields).
- Run the script:
python form_filler.py - Quickly switch to the target application and hover your mouse over the first text box.
- Wait for the countdown to finish.
