使用Python在Excel中重命名工作表； 引用工作表名称的单元格值

Question

I have been working on a project using Python to build a program that simplifies changes to be made in Microsoft Excel. I am attempting to loop through a workbook to rename all of the sheets. The main difference my problem has from what I have read is that I am renaming the sheets based on a value in a cell using the following code:

"""Loop through each worksheet and rename the sheet using a value from the sheet."""
for i in wb:
    ws = wb.active
    c = ws['A1']
    ws.title = c + (i + 1)
    print(sheet.title)

If someone could clarify what the issue is I would greatly appreciate your assistance. I received the following error report:

Traceback (most recent call last):
  File "<stdin>", line 4, in <module>
  File "C:\Users\Que\AppData\Local\Programs\Python\Python37-32\lib\site-packages\openpyxl\workbook\child.py", line 93, in title
    m = INVALID_TITLE_REGEX.search(value)
TypeError: expected string or bytes-like object

I am using Powershell interactive mode to test each piece of code. Please understand I am attempting to access a value in a cell and have made several attempts to change the code to reflect my objective. Your insight and observations are appreciated.

Answer 1

Maybe the code below will solve the problem:

for sheet in wb:
    sheet_name = sheet.title
    first_cell_value = str(sheet['A1'].value)
    sheet.title = first_cell_value + sheet_name + "1"
    print(sheet.title)

This way you are:

• looping through all the sheets on your workbook;
• getting their names;
• getting the value of their first cells (A1) as a string;
• changing their names to first_cell_value + sheet_name + "1" ;
• printing their new names

The error report you are getting is because you are trying to use the cell itself ( c ) instead of the value inside of it ( c.value ) to rename your worksheet, and the cell itself is not a string/byte-like object.
