python - Multiple styles in one cell in openpyxl -

i wrote python program produces invoices in specific form .xlsx files using openpyxl. have general invoice form excel workbook , program copies form , fills details specific client (eg. client refernce number, price, etc.) read .txt file.

the program works perfectly. problem form contains cell has multiple styles: half of letters red , rest black , there size difference. cell not edited in program (it same in invoices), after rest worksheet edited program cell keeps first style (the red letters).

why openpyxl changes cell since don't edit it? openpyxl support multiple styles, or have split letters different styles in seperate cells?

openpyxl not support multiple styles within individual cell.
