Find last filled column in openpyxl

[Pedroski55]

These 2 give you the maximum column and row:

maxRowSourceFile = sourceFile[sheet].max_row
maxColSourceFile = sourceFile[sheet].max_column

This will copy the last column and put it in the column after that.

def myApp():
    import openpyxl

    # the folder with the XL file
    folder = 'temp'
    # the course
    course = '20BE'
    pathToTT = f'/home/pedro/{folder}/{course}/'
    tt = f'{folder}_{course}latestPyMade_newest.xlsx'
    sourceFile = openpyxl.load_workbook(pathToTT + tt)
    sourceSheetNames = sourceFile.sheetnames
    for sheet in sourceSheetNames:       
        maxRowSourceFile = sourceFile[sheet].max_row
        maxColSourceFile = sourceFile[sheet].max_column
        print('Maximum row for sheet', sheet, 'is', maxRowSourceFile)
        print('Maximum column for sheet', sheet, 'is', maxColSourceFile)
        
    for sheet in sourceSheetNames:       
        maxRowSourceFile = sourceFile[sheet].max_row
        maxColSourceFile = sourceFile[sheet].max_column
        for rowNum in range(1, maxRowSourceFile + 1): # +1 to get the last row
            # get the value in the last column
            last_col_value = sourceFile[sheet].cell(row=rowNum, column=maxColSourceFile).value
            # write the value of the last column to the next column
            # the values will be written without any kind of formatting
            sourceFile[sheet].cell(row=rowNum, column=maxColSourceFile+1, value=last_col_value)

    # openpyxl does not have a file.close() open files remain open until your program is finished
    savename = 'changed_sourceFile.xlsx'
    sourceFile.save(pathToTT + savename)
    print('Last column copied to the next column up and saved to', pathToTT + savename)
    print('All done!')

For formatting from openpyxl look at:

from openpyxl.styles import Font
from openpyxl.utils import get_column_letter
from openpyxl.styles import Alignment  
from openpyxl.drawing.image import Image
