I want to create a new worksheet in my existing excel file through a python code. I am using openpyxl module. I used create_sheet method but not working..plz help. my code is show below
import openpyxl as op
file=op.load_workbook('C:/Users/pavan m sunder/Desktop/hotelpythondata.xlsx')
file.create_sheet('newsheet')
I hope that's "import openpyxl as op" and not just "openpyxl as op"
After creating the sheet, you also need to save the excel.
import openpyxl as op
xlfile = 'C:/Users/pavan m sunder/Desktop/hotelpythondata.xlsx'
file=op.load_workbook(xlfile)
file.create_sheet('newsheet')
file.save(xlfile) # You can save it as the same file or specify another path/ filename

I need to add a new empty column in between two columns of an existing excel using xlwings. How do I do that?
I need to use xlwings library itself as the project requirements need that library.
Please help me with the code
I am using this code :
import xlwings as xw
from xlwings.constants import DeleteShiftDirection
wb = xw.Book('input_file.xlsm')
wb.sheets['Sheet 1'].delete()
wb.sheets['Sheet 3'].delete()
sheet = wb.sheets['Sheet 2']
sheet.range('1:1').api.Delete(DeleteShiftDirection.xlShiftUp)
sheet.pictures[0].delete()
wb.sheets['Sheet 2'].range('I:I').insert()
wb.save('input_file.xlsm')
As #moken already commented:
# import the lib
import xlwings as xw
# create a workbook
wb = xw.Book()
# for the first sheet (index 0) in range from A to A insert a column
wb.sheets[0].range('A:A').insert()
If you already have an xml file, you may open it with pandas:
import pandas as pd
# new dataframe
df = pd.read_xml("path.xml")
Then it is up to you how to manipulate with the data
I want to handle Open,creat new file, Saveas, delete etc using python
Use pyexcel to handle the file.
You don't handle the software (excel.exe) therefore you handle the files such as .csv or .xlsx.
$ pip install pyexcel
Here the documentation:
Read the docs pyexce
Sample:
>>> import pyexcel
>>> reader = pyexcel.Reader("example.csv""")
>>> print reader[1][1]

Openpyxl is a great module that I have been using to work with Excel files (docs):
pip3 install openpyxl
creating and saving a Workbook:
from openpyxl import Workbook
wb = Workbook()
wb.save('balances.xlsx')
Selecting a specific worksheet:
worksheet = wb["Sheet1"]
Reading and writing data from worksheet:
c = ws['A4']
ws['A4'] = 4
or:
d = ws.cell(row=4, column=2)
I have downloaded a module called openpyxl which I intend to use to extract data (parts numbers) out from our many Excel files and then write them into a single file. I have not used Python much and am wondering how I could alter the the following code so that the script would open a spreadsheet, run some code on that spreadsheet, and then move onto the next one. If it was a list or a string of some sort I could write for loops for it but for actual spreadsheets I don't know how this would be done.
Can anyone offer any advice on how to loop through documents like this?
from openpyxl import load_workbook
>>> wb2 = load_workbook('test.xlsx')
>>> print wb2.get_sheet_names()
['Sheet2', 'New Title', 'Sheet1']
You could get a list of the spreadsheets with os.listdir() and then extract the data using a for loop, like so:
import os
from openpyxl import load_workbook
path = "path/to/folder" # The folder containing the spreadsheets
sheets = os.listdir(path)
for sheet in sheets:
wb2 = load_workbook(os.path.join(path, sheet))
print(wb2.get_sheet_names())
wb2._archive.close()
I have an xlsx file with 1 sheet.
I am trying to open it using python 3 (xlrd lib), but I get an empty file!
I use this code:
file_errors_location = "C:\\Users\\atheelm\\Documents\\python excel mission\\errors1.xlsx"
workbook_errors = xlrd.open_workbook(file_errors_location)
and I have no errors, but when I type:
workbook_errors.nsheets
I get "0", even the file has some sheets... when I type:
workbook_errors
I get:
xlrd.book.Book object at 0x2..
any help? thanks
You can use Pandas pandas.read_excel just like pandas.read_csv:
import pandas as pd
file_errors_location = 'C:\\Users\\atheelm\\Documents\\python excel mission\\errors1.xlsx'
df = pd.read_excel(file_errors_location)
print(df)
There are two modules for reading xls file : openpyxl and xlrd
This script allow you to transform a excel data to list of dictionnaries using xlrd
import xlrd
workbook = xlrd.open_workbook('C:\\Users\\atheelm\\Documents\\python excel mission\\errors1.xlsx')
workbook = xlrd.open_workbook('C:\\Users\\atheelm\\Documents\\python excel mission\\errors1.xlsx', on_demand = True)
worksheet = workbook.sheet_by_index(0)
first_row = [] # The row where we stock the name of the column
for col in range(worksheet.ncols):
first_row.append( worksheet.cell_value(0,col) )
# tronsform the workbook to a list of dictionnary
data =[]
for row in range(1, worksheet.nrows):
elm = {}
for col in range(worksheet.ncols):
elm[first_row[col]]=worksheet.cell_value(row,col)
data.append(elm)
print data
Unfortunately, the python engine 'xlrd' that is required to read the Excel docs has explicitly removed support for anything other than xls files.
So here's how you can do it now -
Install openpyxl:
https://openpyxl.readthedocs.io/en/stable/
Change your pandas code to:
pandas.read_excel('cat.xlsx', engine='openpyxl')
Note: This worked for me with the latest version of Pandas (i.e. 1.1.5). Previously, I was using version 0.24.0 and it didn't work so I had to update to latest version.
Another way to do it:
import openpyxl
workbook_errors = openpyxl.Workbook()
workbook_errors = openpyxl.load_workbook(file_errors_location)
import string
import xlrd
import xlsxwriter
workbook = xlsxwriter.Workbook('C:\T\file.xlsx')
worksheet = workbook.add_worksheet()
book = open_workbook(r'C:\T\test.xls','r')
sheet = book.sheet_by_index(0)
for row_index in range(sheet.nrows):
for col_index in range(sheet.ncols):
print sheet.cell(row_index,0).value
x = sheet.cell(row_index,0).value
worksheet.write_string(row_index,col_index,x)
workbook.close()
I'm a skiddy to python. Here i'm trying to read the xls file with xlrd for data and copy it to another xlsx file through xlsxwriter module. but the data won't get pasted in the created xlsx sheet. Please guide me through this. Above is my exact code. Please correct me if any wrong.
A volley of Thanks in advance.
Your example program almost works. Mainly it needs the open_workbook() method to be prefixed with a class and it is better to use XlsxWriter write() instead of write_string() unless you are sure that all the data you are reading is of a string type. Also, the program was only reading values from column 0.
Here is the same example with those changes in place. I've also renamed the variables in_ and out_ to make it clearer which module is calling which method:
import xlrd
import xlsxwriter
out_workbook = xlsxwriter.Workbook('file.xlsx')
out_worksheet = out_workbook.add_worksheet()
in_workbook = xlrd.open_workbook(r'test.xls', 'r')
in_worksheet = in_workbook.sheet_by_index(0)
for row_index in range(in_worksheet.nrows):
for col_index in range(in_worksheet.ncols):
cell_value = in_worksheet.cell(row_index, col_index).value
out_worksheet.write(row_index, col_index, cell_value)
print cell_value
out_workbook.close()
