Replace part of a cell value with blank with openpyxl

Question

I have a spread sheet where Column A has a list of computer names with domain\\ preceding the computer name. I am trying to use openpyxl to remove the domain\\ and leave just the computer names. Here is the code I have tried. There is no error however the script does not change anything on the spreadsheet.

import openpyxl
    excelFile = openpyxl.load_workbook('C:\Users\user1\Documents\file.xlsx')
    sheet1 = excelFile.get_sheet_by_name('Sheet1')
    currentRow = 1
    for eachRow in sheet1.iter_rows():
        if sheet1.cell(row=currentRow, column=1).value == "'domain\'":
            sheet1.cell(row=currentRow, column=1).value = ""
        currentRow += 1
    excelFile.save('C:\Users\user1\Documents\file.xlsx')

The easiest way is to replace the cell value with a trimmed string.

import openpyxl
filename = r'C:\Users\user1\Documents\file.xlsx'
excelFile = openpyxl.load_workbook(filename)
sheet1 = excelFile.active
for row in sheet1.iter_rows(min_col=1, max_col=1):
    for cell in row:
        if 'domain\\' in cell.value:
            cell.value = cell.value[7:] #This will replace the cell value with a trimmed string
excelFile.save(filename)
