reading and updating sheets in an xlsm file using pandas while preserving the vba code

You can do this easily with pandas

import pandas as pd
import xlrd

# YOU MUST PUT sheet_name = None TO READ ALL CSV FILES IN YOUR XLSM FILE
df = pd.read_excel('YourFile.xlsm', sheet_name = None)

# prints all sheets
print(df)

Ah, I see. I still can't tell what you are doing, but here are a few general samples of code to get Python to communicate with Excel.

Read contents of a worksheet in Excel:

   import pandas as pd
from pandas
import ExcelWriter
from pandas
import ExcelFile

df = pd.read_excel('C:\\your_path\\test.xls', sheetname = 'Sheet1')

   **
   ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** ** **

   Use Python to run Macros in Excel:
   import os
import win32com.client

#Launch Excel and Open Wrkbook
xl = win32com.client.Dispatch("Excel.Application")
xl.Workbooks.Open(Filename = "C:\your_path\excelsheet.xlsm") #opens workbook in readonly mode.

#Run Macro
xl.Application.Run("excelsheet.xlsm!modulename.macroname")

#Save Document and Quit.
xl.Application.Save()
xl.Application.Quit()

#Cleanup the com reference.
del xl

Write, from Python, to Excel:

   import xlsxwriter

# Create an new Excel file and add a worksheet.
workbook = xlsxwriter.Workbook('C:/your_path/ranges_and_offsets.xlsx')
worksheet = workbook.add_worksheet()

# Widen the first column to make the text clearer.
worksheet.set_column('A:A', 20)

# Add a bold format to use to highlight cells.
bold = workbook.add_format({
   'bold': True
})

# Write some simple text.
worksheet.write('A1', 'Hello')

# Text with formatting.
worksheet.write('A2', 'World', bold)

# Write some numbers, with row / column notation.
worksheet.write(2, 0, 123)
worksheet.write(3, 0, 123.456)

workbook.close()

I have a requirement to read an xlsm file anycodings_vba and update some of the sheets in the file. I anycodings_vba want to use pandas for this purpose.,Also, is there a way I can open the "xlsm" anycodings_vba file itself rather than the "xlsx" anycodings_vba counterpart using pd.ExcelWriter?,With this I don't see the VBA macros anycodings_vba attached to "test.xlsm". The result is the anycodings_vba same even if I write it to the anycodings_vba "original.xlsm" file.,Ah, I see. I still can't tell what you anycodings_excel are doing, but here are a few general anycodings_excel samples of code to get Python to anycodings_excel communicate with Excel.

Extracted the VBA_project.bin out of the anycodings_vba original.xlsm file and then

writer = pd.ExcelWriter('original.xlsx', engine = 'xlsxwriter')
workbook = writer.book
workbook.filename = 'test.xlsm'
workbook.add_vba_project('vbaProject.bin')
writer.save()

You can do this easily with pandas

import pandas as pd
import xlrd

# YOU MUST PUT sheet_name = None TO READ ALL CSV FILES IN YOUR XLSM FILE
df = pd.read_excel('YourFile.xlsm', sheet_name = None)

# prints all sheets
print(df)

An Excel xlsm file is exactly the same as an xlsx file except that is contains an additional vbaProject.bin file which contains functions and/or macros. Excel uses a different extension to differentiate between the two file formats since files containing macros are usually subject to additional security checks.,Excel files that contain functions and macros should use an xlsm extension or else Excel will complain and possibly not open the file:,The vba_extract.py utility is used to extract the vbaProject.bin binary from an Excel 2007+ xlsm file. The utility is included in the XlsxWriter examples directory and is also installed as a standalone executable file:,Instead a workaround is used to extract vbaProject.bin files from existing xlsm files and then add these to XlsxWriter files.

$ vba_extract.py macro_file.xlsm
Extracted: vbaProject.bin

workbook.add_vba_project('./vbaProject.bin')

worksheet.write_formula('A1', '=MyMortgageCalc(200000, 25)')

workbook = xlsxwriter.Workbook('macros.xlsm')

import xlsxwriter

# Note the file extension should be.xlsm.
workbook = xlsxwriter.Workbook('macros.xlsm')
worksheet = workbook.add_worksheet()

worksheet.set_column('A:A', 30)

# Add the VBA project binary.
workbook.add_vba_project('./vbaProject.bin')

# Show text
for the end user.
worksheet.write('A3', 'Press the button to say hello.')

# Add a button tied to a macro in the VBA project.
worksheet.insert_button('B3', {
   'macro': 'say_hello',
   'caption': 'Press Me',
   'width': 80,
   'height': 30
})

workbook.close()

worksheet.insert_button('B3', {
   'macro': 'ThisWorkbook.say_hello'

5 days ago Example 2: Write DataFrame to a specific Excel Sheet. You can write the DataFrame to a specific Excel Sheet. The step by step process is: Have your DataFrame ready. Create an Excel Writer with the name of the desired output excel file. Call to_excel () function on the DataFrame with the writer and the name of the Excel Sheet passed as arguments. , Python Examples. You can save or write a DataFrame to an Excel file or a specific Sheet in the Excel file using to_excel() method of DataFrame class. You have to install openpyxl module to work with Excel file functions in pandas. To install openpyxl using pip run the following command. , Is there also a possibility to write the DataFrameinto a .xlsmExcel file? This is actually more or less the same as .xlsx, but with the possibility enabled to store VBA macros within the file. I need this because I want to insert and run a VBA macro after creating the file. ,Is there also a possibility to write the DataFrame into a .xlsm Excel file?

import pandas as pd df = pd.DataFrame({
   'firstColumn': [5, 2, 0, 10, 4],
   'secondColumn': [9, 8, 21, 3, 8]
}) print(df) df.to_excel('test.xlsx')

The following features cannot be saved in macro - free workbooks: VB project.To save a file with these features, click No, and then choose a macro - enabled file type in the File Type list.To
continue saving as macro - free workbook, click Yes.

Excel cannot open the file 'myFilename.xlsm'
because the file format or file extension is not valid.Verify that the file has not been corrupted and that the file extension matches the format of the file.
