I am trying to load an existing Excel file and create a new sheet inside that workbook, but my code is not working using openpyxl.
rb = load_workbook("C:\Raw_Dump.xlsx")
rb.create_sheet("Sheet2")
sheet1 = rb.worksheets[0]
Any help would be appreciated.
You have to save the workbook to the same filename:
rb.save(r"C:\Raw_Dump.xlsx")
full working example:
import openpyxl
ws_name = r"Raw_Dump.xlsx"
rb = openpyxl.load_workbook(ws_name)
rb.create_sheet("Sheet2")
rb.save(ws_name)
I spent a long time searching this and found the best way is to do sheet removal. The code below worked for me:
for sheet in wb.sheetnames:
if sheet not in "MY_SHEET_I_WANNA_KEEP":
rm_sheet = wb[sheet];
wb.remove_sheet(rm_sheet)
wb.save("JustOneSheet.xlsx")

I use Openpyxl in Python to write some data in an Excel file using Workbook.
When I want to save the workbook to a file, I can only provide a filename argument, so I can not write files in other directories.
here is my sample code:
import openpyxl
file_name = "sample.xlsx"
wb = openpyxl.Workbook()
# writing some data to workbook
wb.save(filename=file_name)
I have checked the documentation via this link and found nothing more.
Python: 3.10.7
Openpyxl: 3.0.10
Can you help me provide workarounds to solve this problem?
You can indicate a full path + filename, and it will create a file where you need it:
wb = Workbook()
wb.save(r'D:\folder\folder\folder\Filename.xlsx')
I need an Excel workbook to open on sheet1 or by that sheets name. I'm using xlwings to alter a workbook with several sheets. Everything works fine but when the file is opened in Excel it opens on the last sheet that has been altered. I can't seem to find an answer. Please help. Thanks
This is what might help you
# load Workbook
workbook= xw.Book('path_file')
#acivate sheet by name
sheet = workbook.sheets.activate('Sheet_Name')
if that doesn't work try
sheet = workbook.sheets["Sheet_Name"]
I am using Python 3.7 and using OpenPyxl to read the sheet names from a large excel workbook (29MB) with 10 tabs.
import openpyxl
from openpyxl import load_workbook
wb = load_workbook(filename='h:\\Master_Portfoliio.xlsx')
print(wb.sheetnames)
The code above works for smaller files but when I use the same code for this file, the code just hangs. I would like to read the sheet names and then remove a tab and then copy a tab from another excel workbook into this workbook.
Have you tried the read_only = True flag?
wb = load_workbook(filename='h:\\Master_Portfoliio.xlsx', read_only = True)
I want to insert a Image(object) in MS-Excel Report which i am generating using openpyxl utility. Is there a way to do it using some python utility?
Openpyxl allows you to write images into your Excel files! Here it is in the official documentation.
import openpyxl
wb = openpyxl.Workbook()
ws = wb.worksheets[0]
picture = openpyxl.drawing.Image('/path/to/picture')
picture.anchor(ws.cell('cell to put the image'))
ws.add_image(picture)
wb.save('whatever you want to save the workbook as')
This code of course refers to creating a new workbook and adding the image into it. To add the image to your preexisting workbook you would obviously just load that workbook using load_workbook.
I've been using the openpyxl module to do some processing on some .xlsx files. I've been trying to figure out how to iterate over sheets in a workbook. I'm not sure if I can get it figured out. I've tried the 2 codes below which both return empty results. My .xlsx file has about 20 sheets, so something should return.
The one thing I couldn't find on the internet, is how to set a workbook to an actual workbook. Usually I am writing to a workbook, so I just initialize it by setting a variable to en empty workbook workbook = Workbook() but in this case, I am unsure if I can open a workbook by doing workbook = Workbook(r"C:\Excel\LOOKUP_TABLES_edited.xlsx")
If anyone can identify what it is I am doing wrong, I would appreciate it.
Here is my code:
workbook = Workbook(r"C:\Excel\LOOKUP_TABLES_edited.xlsx")
for sheet in workbook.worksheets:
print sheet
# or
for sheet in workbook.worksheets:
print sheet.title
Open the workbook via load_workbook() and iterate over worksheets:
from openpyxl import load_workbook
wb = load_workbook(r"C:\Excel\LOOKUP_TABLES_edited.xlsx")
for sheet in wb.worksheets:
print(sheet)
Here's one if you need active worksheets for your code
for sheet in wb:
ws = wb[sheet]
print('Now in sheet: ' + ws.title)
To print titles of all sheets in a workbook:
from openpyxl import load_workbook
wb = load_workbook(r"C:\Excel\LOOKUP_TABLES_edited.xlsx")
print(wb.sheetnames)
I struggled a bit with the whole "workbook.active" and didn't know how to get around it so I tried a little bit of everything and here is what worked well for me!
for sheet in workbook.sheetnames[2:len(workbook.sheetnames)]:
ws = workbook[value]
for val in ws.iter_rows(min_row=11, max_row=21, min_col=2, max_col=10, values_only=True):
print(str(sheet) + " " + str(val))
This will print the sheet name starting with the third sheet, since that's what I needed, as well as all the cell values referenced. The only other thing is this prints a list and if you want to iterate through each value and pull out "0s" or "None" values, then you'll need another loop. Hope this helps whoever else is looking!
