from openpyxl import load_workbook
wb = load_workbook("C:\op.xlsx")
ws = wb.active
This is the code I have so far as I don't know what to do next so pls help me.
Try:
ws.delete_rows(1, ws.max_row)
You could also delete the sheet and create another one:
del wb[wb.active.title]
wb.create_sheet()
See

I am getting a BadZipFile error while using the load_workbook function.
PANEL_PATH = "C:/Test/panel_ph.xlsx"
wb = Workbook()
wb.save(PANEL_PATH)
panel_writer = pd.ExcelWriter(PANEL_PATH, engine='openpyxl')
panel_writer.book = load_workbook(PANEL_PATH,read_only=False)
Can someone please suggest how to resolve it.
Thanks,

Using pandas with the openpyxl engine I want to open an excel woorkbook and add a sheet.
Because, the sheets are growing and getting quit big I want to create a new sheet without reading all the other sheet.
So instead of xlsxwriter, I did start using openpyxl, however I get the following issue that the file gets damaged and needs to recovered by excel.
After that, when I run it a second time, I get the python error that the excel file is 'raise BadZipFile("File is not a zip file")'.
This my test code:
import openpyxl
import pandas
from pandas import ExcelWriter
from pandas import ExcelFile
from openpyxl import Workbook
from openpyxl import load_workbook
sheet1 = 'sheet1'
sheet2 = 'sheet2'
if os.path.exists(filename):
workbook = openpyxl.load_workbook(filename)
else:
workbook = Workbook()
writer = pandas.ExcelWriter(filename, engine='openpyxl')
writer.book = workbook
df_1.to_excel(writer, sheet_name=sheet1)
writer.save()
writer.close()
time.sleep(2) # to give it some time. But doesn't help :(
if os.path.exists(filename):
workbook = openpyxl.load_workbook(filename)
else:
workbook = Workbook()
writer = pandas.ExcelWriter(filename, engine='openpyxl')
writer.book = workbook
df_2.to_excel(writer, sheet_name=sheet2)
writer.save()
writer.close()
Any suggestions how to solve this? Or do I miss something?
btw, excel 365 - 16.46 macOS
here is my code:
import openpyxl as op
from openpyxl import Workbook
from openpyxl import load_workbook
from openpyxl import worksheet
path = ...
op.load_workbook(path)
wb = Workbook()
ws2 = wb.create_sheet('Sheet2')
wb.save(filename = 'NameOfTheFile.xlsx')
Now everything works, except saving the file, when I add:
print(wb.sheetnames)
it does print out the Sheet2 I just added, but for some reason when I go to the documents where the file is, it does not update it, that sheet is nowhere to be found.
I am trying to open and format a specific Excel worksheet. However I am having trouble trying to find out how to look at a specific worksheet.
The code I'm trying to use to open the workbook and go to a specific worksheet and then change the font for specific cells is:
from openpyxl import Workbook
def applyValidations(path,tabname):
workbook = Workbook(path)
worksheet = workbook[tabname]
c = worksheet['A1:A5']
c.font = Font(size=22)
The error I'm getting is:
KeyError: 'Worksheet Department Data does not exist.'
Department Data is the name of the worksheet which does exist in the workbook.
Here's some code I use regularly with openpyxl, which may solve your Q:
from openpyxl import load_workbook
wb = load_workbook(filename=data_file, read_only=True)
ws = wb.active
print(wb.sheetnames)
I want to do something like this:
import openpyxl as x
wb = x.load_workbook(filename)
# do some edit to the workbook
wb.save(filename)
The file specified by the filename is opening in Excel. Excel is locking the file so I will get permission denied error running the above code. Is there a way to edit/save it?
from openpyxl import load_workbook
ifile = 'Whales.xlsx'
wb = load_workbook(filename=ifile)
# do some edit to the workbook
wb.save(ifile)
