openpyxl writes formulas as strings with no cached values . Until you recalculate, every formula cell reads back as None to anything reading cached values — pandas, load workbook(data only=True), and most previewers. Use it to make implementation decisions and avoid common dead ends.
A .pptx is a ZIP archive of XML files. Choose your approach by task:. Use it to make implementation decisions and avoid common dead ends.

If you need to fill out a PDF form, first check to see if the PDF has fillable form fields. Run this script from this file's directory: python scripts/check fillable fields , and depending on the result go to either the "Fillable fields" or "Non-fillable fields" and follow thos. Use it to ground design choices in named patterns, trade-offs and examples.
