Create Named Cells In Multiple Sheets With Same Name Openpyxl

I am creating excel file with multiple sheets. In every sheet i need same define name with group of rows and columns.we can create it manually but through program how to achieve th

Solution 1:

I think the named ranges are global to the workbook, not local to each sheet. Which is hinted at by the error message you're getting:

DefinedName with the same name and scope already exists

So you'd have to give those different names

wb = openpyxl.load_workbook(file.xlsx)
sheet1 = wb['sheet1']
sheet2 = wb['sheet2']
wb.create_named_range('sales1', sheet1 , '$B$11:$B$35')
wb.create_named_range('sales2', sheet2 , '$B$11:$B$35')

or a more DRY solution:

wb = openpyxl.load_workbook(file.xlsx)
sheets = []
for sheet_no inrange(1,3):
    sheets[sheet_no] = wb[f'sheet{sheet_no}'] # note pre python 3.6 you should change f'sheet{sheet_no}' to 'sheet{}'.format(sheet_no)
    wb.create_named_range(f'sales{sheet_no}', sheets[sheet_no], '$B$11:$B$35')
