No suelo necesitar VBA, así que prefiero hacer cosas de excel en python + openpyxl
from docx import Document #word docx py library
import openpyxl #excel py library
from openpyxl.styles import Color, PatternFill, Font, Border
from openpyxl.styles import colors
from openpyxl.cell import Cell
import re #regular expressions
import os #work with system
wb = openpyxl.load_workbook('test.xlsx') #open needed document
redFill = PatternFill(start_color='FFFF0000',
end_color='FFFF0000',
fill_type='solid') #function to fill bad cells red
n = 0
print (wb.sheetnames) #print all sheetnames to ensure theres no hidden
for sheet in wb.worksheets: #cycle through sheets in excel file
# get max row count
max_row=sheet.max_row
# get max column count
max_column=sheet.max_column
for i in range(1,max_row+1):
# iterate over all columns
for j in range(1,max_column+1): #cycle through all rows and columns
# get particular cell value
cell_obj=sheet.cell(row=i,column=j)
s = re.search('[^-*+()!№;%:?@#$%^&;:_=/\a-zA-Z0-9\ а-яА-Я°\".,,.«»<>ёЁ]', str(cell_obj.value)) #find bad symbols with regular expression
#^ find not normal characters
#s = re.search('[\n]', str(cell_obj.value)) find line end
if s:
print(n, " ", i, " ", j) #sheet, row, col
#print("^", s, "^") print bad symbol
#sheet.cell(row=i,column=j).fill = redFill
#color current cell wth spec chars red
print(n)
n+=1
wb.save("test.xlsx") #save redacted book
