Save cellrange from excel spreadsheet as image in python - python-3.x

Question

I am currently working on a Python script that saves screenshots from an Excel file using the excel2image module.
My code is pretty easy:
import excel2img
excel2img.export_img(Workpath + "/" + "CB_TEMP.xlsx", "alarm_BB1.png", "Deckblatt", "A2:C20")
Unfortunately I always get the following error message:
---------------------------------------------------------------------------
AttributeError Traceback (most recent call last)
<ipython-input-18-a119e849f4d5> in <module>
----> 1 excel2img.export_img(Workpath + "/" + "CB_TEMP.xlsx", "alarm_BB1.png", "Deckblatt", "A2:C20")
~\anaconda3\lib\site-packages\excel2img\excel2img.py in export_img(fn_excel, fn_image, page, _range)

~\anaconda3\lib\site-packages\win32com\client\__init__.py in __getattr__(self, attr)

472 if args is None:
--> 473 raise AttributeError("'%s' object has no attribute '%s'" % (repr(self), attr))
474 return self._ApplyTypes_(*args)
475
AttributeError: '<win32com.gen_py.Microsoft Excel 16.0 Object Library.Range instance at 0x2460934736048>' object has no attribute 'parent'
I have already tried several workarounds but I can't get it to work. Sometimes it works like magic, but mostly only after a reboot and deleting the data in C:/Users/patrick/AppData/Temp/gen_py.
I have a feeling something is clashing in the code with the win32com module I use in a function before to convert an XLSB file to an XLSX file:
def ConvertExcel(excel_filepath, Workpath):
excel = win32com.client.gencache.EnsureDispatch('Excel.Application')
xlsb_doc = excel.Workbooks.Open(os.path.abspath(excel_filepath))
excel_sheets = os.path.abspath(Workpath) + "\\CB_TEMP.xlsx"
xlsb_doc.SaveAs(excel_sheets, 51)
xlsb_doc.Close()
excel.Quit()
del excel
return excel_sheets
Maybe anybody can help me out?
Kind regards,
Patrick

I fixed this by dropping the excel2img module.
I wrote the code new in xlwings with Pillow which works even faster than in excel2img:
import xlwings as xw
from PIL import ImageGrab
try:
excel_app = xw.App(visible=False)
excel_book = excel_app.books.open(excel_filepath)
for image in df_img.index:
excel_book.sheets[df_img.at[image, "sheet_name"]][
df_img.at[image, "Range"]].copy(destination=None)
img = ImageGrab.grabclipboard()
img.save(df_img.at[image, "Bild"], 'JPEG')
excel_book.close()
excel_app.quit()
excel_app.kill()
except:
pass
