How can i write on an XLS file using python?

I want to open a .xls file on python modify some rows and rewrite the new content on the same file because i use a macro to synchronise the data with SharePoint.
What libraries can i use?

You can do it using pandas with :
import pandas as pd
df = pd.read_excel('path/file.xls')
# modifications here ....
df.to_excel('path/file.xls')

Have you tried openpyxl?
It's very easy to modify xlsx file using this library.
from openpyxl import Workbook
wb = Workbook()
# grab the active worksheet
ws = wb.active
# Data can be assigned/updated directly to cells
ws['A1'] = 42
# Rows can also be appended
ws.append([1, 2, 3])
# Python types will automatically be converted
import datetime
ws['A2'] = datetime.datetime.now()
# Save the file
wb.save("sample.xlsx")
For more details you can refer to the openpyxl documentation.

How can i write a csv file to an excel sheet using openpyxl?

I am having some trouble writing an csv to an excel workbook. I have tried a series of options but i think openpyxl migth do job... however i cannot find a way to do this.
e.g.
from openpyxl import Workbook
import openpyxl
import csv
#ceate workbook
wb = openpyxl.Workbook()
TOP3 = wb.sheetnames
wb.create_sheet(title='metrics')
wb.save(filename='Test.xlsx')
sheet = wb["TOP3"]
#write an existing csv to the sheet above:
with open('metrics.csv', 'r') as f:
reader = csv.reader(f)
for row in reader:
for i in range(0,len(row)):
sheet[f"""A{i}"""] = row
above does not work! How can I read a csv file into an excel workbook? I would like to automate this. I basically want to import my metrics csv into the metrics tab of my workbook

I suggest using pandas
import pandas as pd
df = pd.read_csv('metrics.csv')
df.to_excel('test.xlsx', sheet_name='metrics', index=False)

How to read a specific row in excel file using python

I want to read single row from an Excel_file1, Sheet1, Row number 7 using python, any help?

First install xlrd
pip install xlrd
then open python file and
import xlrd
# Give the location of the file
loc = ("path of file")
# To open Workbook
wb = xlrd.open_workbook(loc)
sheet = wb.sheet_by_index(0)
print(sheet.row_values(7))
location is relative path not absolute path.
To read more about xlrd and its usage visit https://xlrd.readthedocs.io/en/latest/
Happy coding.

You can also use pd.read_excel of pandas library:
You would need to install pandas and xlrd first:
import pandas as pd
import xlrd
df = pd.read_excel('abc.xlsx', sheet_name='Sheet1')
Now, you can filter your dataframe to get any specific row using iloc
df.iloc[6] ## This will give you 7th row

Write data into existing excel file and making summary table

I have to write some data into existing xls file.(i should say that im working on unix and couldnt use windows)
I prefer work with python and have tried some libraries like xlwt, openpyxl, xlutils.
Its not working, cause there is some filter in my xls file. After rewriting this file filter is dissapearing. But i still need this filter.
Could some one tell me about options that i have.
help, please!
Example:
from xlutils.copy import copy
from xlrd import open_workbook
from xlwt import easyxf
start_row=0
rb=open_workbook('file.xls')
r_sheet=rb.sheet_by_index(1)
wb=copy(rb)
w_sheet=wb.get_sheet(1)
for row_index in range(start_row, r_sheet.nrows):
row=r_sheet.row_values(row_index)
call_index=0
for c_el in row:
value=r_sheet.cell(row_index, call_index).value
w_sheet.write(row_index, call_index, value)
call_index+=1
wb.save('file.out.xls');
I also tried:
import xlrd
from openpyxl import Workbook
import unicodedata
rb=xlrd.open_workbook('file.xls')
sheet=rb.sheet_by_index(0)
wb=Workbook()
ws1=wb.create_sheet("Results", 0)
for rownum in range(sheet.nrows):
row=sheet.row_values(rownum)
arr=[]
for c_el in row:
arr.append(c_el)
ws1.append(arr)
ws2=wb.create_sheet("Common", 1)
sheet=rb.sheet_by_index(1)
for rownum in range(sheet.nrows):
row=sheet.row_values(rownum)
arr=[]
for c_el in row:
arr.append(c_el)
ws2.append(arr)
ws2.auto_filter.ref=["A1:A15", "B1:B15"]
#ws['A1']=42
#ws.append([1,2,3])
wb.save('sample.xls')
The problem is still exist. Ok, ill try to find machine running on windows, but i have to admit something else:
There is some rows like this:
enter image description here
Ive understood what i was doing wrong, but i still need help.
First of all, i have one sheet that contains some values
Second sheet contains summary table!!!
If i try to copy this worksheet it did wrong.
So, the question is : how could i make summary table from first sheet?

Suppose your existing excel file has two columns (date and number).
This is how you will append additional rows using openpyxl.
import openpyxl
import datetime
wb = openpyxl.load_workbook('existing_data_file.xlsx')
sheet = wb.get_sheet_by_name('Sheet1')
a = sheet.get_highest_row()
sheet.cell(row=a,column=0).value=datetime.date.today()
sheet.cell(row=a,column=1).value=30378
wb.save('existing_data_file.xlsx')

If you are on Windows, I would suggest you take a look at using the win32com.client approach. This allows you to interact with your spreadsheet using Excel itself. This will ensure that any existing filters, images, tables, macros etc should be preserved.
The following example opens an XLS file adds one entry and saves the whole workbook as a different XLS formatted file:
import win32com.client as win32
import os
excel = win32.gencache.EnsureDispatch('Excel.Application')
wb = excel.Workbooks.Open(r'input.xls')
ws = wb.Worksheets(1)
# Write a value at A1
ws.Range("A1").Value = "Hello World"
excel.DisplayAlerts = False # Allow file overwrite
wb.SaveAs(r'sample.xls', FileFormat=56)
excel.Application.Quit()
Note, make sure you add full paths to your input and output files.

Writing into existing excel file

I have a .xlsx file in which multiple worksheets are there (with some content). I want to write some data into specific sheets say sheet1 and sheet5. Right now I am doing it using xlrd, xlwt, and xlutils copy() function. But is there any way to do it by opening the file in append mode and adding the data and save it (Like as we do it for the text/CSV files)?
Here is my code:
rb = open_workbook("C:\text.xlsx",formatting_info='True')
wb = copy(rb)
Sheet1 = wb.get_sheet(8)
Sheet2 = wb.get_sheet(7)
Sheet1.write(0,8,'Obtained_Value')
Sheet2.write(0,8,'Obtained_Value')
value1 = [1,2,3,4]
value2 = [5,6,7,8]
for i in range(len(value1)):
Sheet1.write(i+1,8,value1[i])
for j in range(len(value2)):
Sheet2.write(j+1,8,value2[j])
wb.save("C:\text.xlsx")

You can do it using the openpyxl module or using the xlwings module
Using openpyxl
from openpyxl import workbook #pip install openpyxl
from openpyxl import load_workbook
wb = load_workbook("C:\text.xlsx")
sheets = wb.sheetnames
Sheet1 = wb[sheets[8]]
Sheet2 = wb[sheets[7]]
#Then update as you want it
Sheet1 .cell(row = 2, column = 4).value = 5 #This will change the cell(2,4) to 4
wb.save("HERE PUT THE NEW EXCEL PATH")
the text.xlsx file will be used as a template, all the values from text.xlsx file together with the updated values will be saved in the new file
Using xlwings
import xlwings
wb = xlwings.Book("C:\text.xlsx")
Sheet1 = wb.sheets[8]
Sheet2 = wb.sheets[7]
#Then update as you want it
Sheet1.range(2, 4).value = 4 #This will change the cell(2,4) to 4
wb.save()
wb.close()
Here the file will be updated in the text.xlsx file but if you want to have a copy of the file you can use the code below
shutil.copy("C:\text.xlsx", "C:\newFile.xlsx") #copies text.xslx file to newFile.xslx
and use
wb = xlwings.Book("C:\newFile.xlsx") instead of wb = xlwings.Book("C:\text.xlsx")
As a user of both modules I prefer the second one over the first one.

For manipulating existing excel files you should use openpyxl. Other common libraries like the ones you are using dont support manipulating existing excel files. A workaround is to
save your output file as a different name - text_temp.xlsx
delete your original file - text.xlsx
rename your output file - text_temp.xlsx to text.xlsx
