xlsx file created with Pandas ExcelWriter requires repair

Question

As stated in the title, the xlsx created with the code below is corrupt.
Can anyone see a problem in my code?

if "O-" in project:
    path = project_folder_order
elif "Q-" in project:
    path = project_folder_quote

book = load_workbook(path)

writer = pd.ExcelWriter(str(path), engine='openpyxl', mode='a')
writer.book = book
writer.sheets = dict((ws.title, ws) for ws in book.worksheets)
worksheet = writer.sheets["Create"]

worksheet.cell(row=int(no_target_lang_len) + 1, column=1).fill = PatternFill(start_color='FFFF00', end_color='FFFF00', fill_type='solid')                                                                          

df1 = pd.read_csv(r"\awsdfpudblapp.xxx.dePlanetKrake\" + project + "\4_Term_TO_DO_" + project + ".csv")
df1_create = df1["Create"]
df1_search = df1["Search"]

df1_create.to_excel(writer, sheet_name="Create", index=False, startcol=0, startrow=1, merge_cells=True)
df1_search.to_excel(writer, sheet_name="Search", index=False, startcol=0, startrow=no_target_lang_len, merge_cells=True)

worksheet.merge_cells(start_row=int(no_target_lang_len) + 1, start_column=1, end_row=int(no_target_lang_len) + 1, end_column=4)

writer.save()
writer.close()

The Excel error message is rather vague:

error052160_01.xml
Errors were detected in file ‘D:Usersxxx4_Term_TODO_Q-21-001727-01.xlsx’
Excel completed file level validation and repair. Some parts of this workbook may have been repaired or discarded.

After letting Excel repair the file, the content does appear, but I need to save it as another version in order to be able to use the file in another application.

I also have the problem with this somewhat shorter code:

if "O-" in project:
    path = project_folder_order
elif "Q-" in project:
    path = project_folder_quote

book = load_workbook(path)
writer = pd.ExcelWriter(path, engine='openpyxl', mode='a')
writer.book = book

df1 = pd.read_csv(r"\awsdfpudblapp.xxx.dePlanetKrake\" + project + "\4_Term_TO_DO_" + project + ".csv")
df1.to_excel(writer, sheet_name="Term candidates", index=False, merge_cells=True)


writer.save()
writer.close()

Answer 1

Instead of using the last lines of your code :

writer.save()
writer.close()

Try to use:

book.save()

My opinion: when you are saving the writer object it is only some part of excel and it is advised to keep the whole excel file, so the book object as an entire excel should save excel without any damage.

Answer 2

I faced this problem before.

In your last line of code.
Just change writer.close() to book.close(). It works fine in my code. May cause from load_workbook and you didn’t close them.
