Python Import Excel Into Database

PYTHON IMPORT EXCEL TO DATABASE

https://code-boxx.com/import-excel-database-python/

NOTES

1. GIST does not allow Excel files... Convert S2_users.csv to S2_users.xlsx on your own.
2. Run unpack.bat (Windows) unpack.sh (Linux/Mac). This will automatically:
   • Create a virtual environment - virtualenv venv.
   • Activate the virtual environment - venv\scripts\activate (Windows) venv/bin/activate (Mac/Linux)
   • Install required modules - pip install openpyxl
   • Create the dummy database - python S1B_create.py
   • Run the import example - python S3_import.py
