Python Flask Display Excel File In HTML Table

PYTHON DISPLAY EXCEL IN HTML TABLE

https://code-boxx.com/excel-html-table-python-flask/

NOTES

  1. GIST does not allow Excel files. Convert S1_dummy.csv to S1_dummy.xlsx on your own, OR generate your own dummy Excel file.
  2. Run unpack.bat (Windows) unpack.sh (Linux/Mac). This will automatically:
    • Create a templates folder, move S3_excel_table.html inside.
    • Create a virtual environment - virtualenv venv.
    • Activate the virtual environment - venv\scripts\activate (Windows) venv/bin/activate (Mac/Linux)
    • Install Flask + PYExcel - pip install openpyxl flask
    • Run python S2_server.py to start the server.
  3. Access http://localhost in your browser.
