I opened a excel file by using the following code:
from openpyxl import load_workbook
wb = load_workbook('path of the file')
DriverTableSheet = wb.get_sheet_by_name(name = 'name of the sheet')
after that I have to append some values in that excel file..
for that I used the following code
DriverTableSheet.cell(row=1, column=2).value="value"
But it is not responding. Can u guys please guide how to write / append a data in that excel file and save that excel file

Open excel，then click file->New->Blank workbook, we can get a blank workbook. We can input some information.
I want to use Python to save the created Excel to the path we set.
import win32com.client
import os
excel = win32com.client.Dispatch("Excel.Application")
xlsx_fullname = os.path.abspath("Book1")
workBook = excel.Workbooks.Open(xlsx_fullname)
excel.ExecuteExcel4Macro("FDSFORCERECALC(False)")
workBook.Save()
workBook.Close(True)
excel.Application.Quit()
I used this code, but I can't use python to select this excel file. It's not working
Change
xlsx_fullname = os.path.abspath("Book1")
workBook = excel.Workbooks.Open(xlsx_fullname)
...
workBook.Save()
to
workBook = excel.ActiveWorkbook
...
workBook.SaveAs(Filename="c:/path/to/your desired filename.xlsx")
I am using Openpyxl to add some data to an existing excel file but unfortunately it also changes the format of my chart (border, background and curves colors) and deletes textbox.
Does anyone know how to prevent these changes ?
Thanks ahead !
A simplified version of my code below and
a screenshot of my excel file
so everyone can reproduce the excel file.
import os
import sys
import pandas as pd
from openpyxl import load_workbook
folder = r'C:\MyFolder'
filename = r'test.xlsx'
writer = pd.ExcelWriter(os.path.join(folder, filename),
engine='openpyxl',
datetime_format='dd/mm/yyyy',
date_format='dd/mm/yyyy')
writer.book = load_workbook(os.path.join(folder, filename))
writer.sheets = {ws.title:ws for ws in writer.book.worksheets}
writer.save()
I am trying to write some data into an excel file (using openpyxl) after a user filled out a form created in Flask (WTForms). The data gets written to an excel sheet, but every time, I open the excel file, I get a below error. I am not sure what I need to do to stop that warning from appearing.
Excel error
My code:
from openpyxl import Workbook, load_workbook
class MyForm(Form):
Name = StringField('Name: ', [InputRequired("Please enter your name.")])
#app.route('/submit', methods=['POST'])
def submit_form():
Name = form.Name.data
workbook = load_workbook(filename='C:\\users\\TestUser\\Desktop\\Test.xlsx')
worksheet = workbook.active
appendData = worksheet.cell(row=1, column=1, value=(Name))
worksheet.append(appendData)
workbook.save('C:\\users\\TestUser\\Desktop\\Test.xlsx')
worksheet.append([Name]) resolves the issue.
I have a basic requirement.
I have a .csv file and a .xlsm file which has a macro. I need to copy the .csv file's contents to that .xlsm file and run the macro. I need to use Python.
Is there any script possible to accomplish this?
Thanks in advance.
file_dir = os.path.dirname(import_file_path)
filename = 'sample.xlsx'
writer = pd.ExcelWriter(filename, engine='xlsxwriter')#Write excel file after write data.(only for write temporary data.)
df.to_excel(writer, sheet_name='ResultSet', index=False)
# ATTACH MACRO AND CREATE .XLSM FILE#
filename_macro = 'sample.xlsm'#Create Macro File.
workbook = writer.book
workbook.filename = filename_macro
workbook.add_vba_project('vbaProject.bin')
writer.save()
if os.path.exists("sample.xlsm"):#Check file
xl = win32com.client.Dispatch("Excel.Application")
xl.Workbooks.Open(os.path.abspath("sample.xlsm"))
xl.Application.Quit() # Comment this out if your excel script closes
del xl
if os.path.exists( 'ResultSet1.xlsx'):#checked file exit or not
# Make duplicate file in user selected directory
xl1 = load_workbook(filename= 'ResultSet1.xlsx')
xl1.save('ResultSet.xlsx')
this link should help to open XLSM via python an fill it with data...

I want to convert a file in tsv format to xls/xlsx..
I tried using
os.rename("sample.tsv","sample.xlsx")
But the file getting converted is corrupted. Is there any other method of doing it?
Here is a simple example of converting TSV to XLSX using XlsxWriter and the core csv module:
import csv
from xlsxwriter.workbook import Workbook
# Add some command-line logic to read the file names.
tsv_file = 'sample.tsv'
xlsx_file = 'sample.xlsx'
# Create an XlsxWriter workbook object and add a worksheet.
workbook = Workbook(xlsx_file)
worksheet = workbook.add_worksheet()
# Create a TSV file reader.
tsv_reader = csv.reader(open(tsv_file, 'rb'), delimiter='\t')
# Read the row data from the TSV file and write it to the XLSX file.
for row, data in enumerate(tsv_reader):
worksheet.write_row(row, 0, data)
# Close the XLSX file.
workbook.close()
You need:
Read the data from the tsv file.
Convert it in what you want them to be.
Write them to an Excel file with openpyxl for xlsx or xlwt for xls.
import csv
from xlsxwriter.workbook import Workbook
# Add some command-line logic to read the file names.
tsv_file = 'sample.tsv'
xlsx_file = 'sample.xlsx'
# Create an XlsxWriter workbook object and add a worksheet.
workbook = Workbook(xlsx_file)
worksheet = workbook.add_worksheet()
# Create a TSV file reader.
tsv_reader = csv.reader(open(tsv_file,'rt'),delimiter="\t")
# Read the row data from the TSV file and write it to the XLSX file.
for row, data in enumerate(tsv_reader):
worksheet.write_row(row, 0, data)
# Close the XLSX file.
workbook.close()
