Please send me your email address and public IP if you are interested in the tool. The customizations are also available (a different store, save the search result to a database, schedule to send a report as an email attachment, etc)

Requirement:

1. Create ‘webscraptool.py’, and copy & paste ‘Main Code’ below (Assuming you have python installed in your machine)
2. Download and save chromedriver under ./driver/ folder. Create ‘driver’ folder in the same folder that you have save ‘webscraptool.py’. (chrome driver download: https://chromedriver.chromium.org/downloads)
3. To create stand-alone ‘webscraptool.exe’, install ‘pyinstaller’ (pip install pyinstaller)
4. Run the code below in command line. This will create the stand-alone ‘.exe’ file.

 pyinstaller -F -w --add-binary "./driver/chromedriver.exe;./driver"
