Deleting first 3 rows in Excel with python

Question

I want to delete the first 3 rows from a specific sheet in Excel with Python (openpyxl).

excel_file = xl.load_workbook('Test.xlsm')
excel_sheet = excel_file('Data')
excel_sheet.delete_rows(idx=0, amount=3)
excel_file.save('Test.xlsm')

But this is not working as expected.

I am getting a long error which ends with:

"for idx, c in enumerate(coordinate):
  TypeError: 'NoneType' object is not iterable"

What does this mean?

Why are the first 3 rows are not deleted?

Answer 1

Try setting the sheet name using square brackets and the first row is row 1 not row 0

excel_sheet = excel_file['Data']
excel_sheet.delete_rows(idx=1, amount=3)
