Read from an Excel spreadsheet, and rename multiple folders with data from XLSX

I am trying to write a script that renames multiple folders in a specific directory, using data from an XLSX sheet, based on their name and timestamp (which are a part of the name as well, in "COMXYZ_YYYYMMDDHHMMSS" format).

Folders in my directory will be in format of "COM123_YYYYMMDDHHMMSS" or "COM12_YYYYMMDDHHMMSS" or "COM1_YYYYMMDDHHMMSS".

The XLSX sheet will have the fields as:

FIELD1 | FIELD2 | FIELD3 | FIELD4 | FIELD5 | FIELD6 | FIELD7
COM12      A        B        C        D        E        F
COM23      A        B        C        D        E        F

I want the folders in my directory with the name "COM12_YYYYMMDDHHMMSS" to be renamed as:

FIELD3_FIELD4_FIELD2_MMDDYYYY_FIELD5_NUMBER_FIELD6_FIELD7

where NUMBER (starting at 1) increases according to the timestamp in the name after the underscore "_", and the date is according to the timestamp in the name as well for that specific COM#.

I have multiple folders with the same COM#, but with different timestamps. So far, I am able to rename 1 folder for each COM#, but the remaining folders are not being renamed.

Appreciate any and all help.

The code I've written so far with help from Aquiles' answer is:

import os
import random
import string
import datetime
import re
import openpyxl
from collections import namedtuple
# Get Directories
directories = [name for name in os.listdir(r'.') if name.startswith('COM')]
# Load workbook
wb = openpyxl.load_workbook('database.xlsx')
ws = wb['Sheet1']
rows = 20
for i in xrange(2, rows + 2):
    if ws['A%s' % i].value >= "":
        folder_to_change = [x for x in directories if x.startswith((ws['A%s' % i].value) + '_')]
        folder_to_change = folder_to_change[0] if len(folder_to_change) > 0 else None
        date_used = {}
        if folder_to_change:
            directories.remove(folder_to_change)
            # print folder_to_change
            folder_parts = folder_to_change.split('_')
            comport = folder_parts[0]
            timestamp = folder_parts[1]
            # print timestamp
            ts = re.search('(....)(....)(......)', timestamp)
            date = ts.group(2) + ts.group(1)
            # print date
            time = comport
            # print time
            date_used[comport] = 1 if comport not in date_used else date_used[comport] + 1
            # print date_used
            # print folder_to_change
            os.rename(
              folder_to_change,
              '{0}_{1}_{2}_{3}_{4}_{5}_{6}_{7}_{8}'.format(
                ws['B%s' % i].value,
                ws['C%s' % i].value,
                ws['G%s' % i].value,
                date,
                ws['D%s' % i].value,
                date_used[comport],
                ws['F%s' % i].value,
                ws['H%s' % i].value,
                ws['I%s' % i].value
                )
              )

I haven't tested this and some of the indexes and stuff may not be the right ones, but you'll get the idea from this. I believe this could work:

import os
import openpyxl
import string

# Get directories
directories = [name for name in os.listdir('.')]

# Load Workbook
wb = openpyxl.load_workbook('file.xls')

# Load first work sheet
ws = wb[0]
rows = 10
dates_used = {}
for i in xrange(2, rows + 2):
    folder_to_change = [x for x in directories if x.startswith(ws['A%s' % i])]
    for y, folder in enumerate(folder_to_change):
        date = folder[8:16]
        os.rename(folder, '{0}_{1}_{2}_{3}_{4}_{5}_{6}_{7}'.format(
            ws['C%s' % i], ws['D%s' % i], ws['B%s' % i], date, ws['E%s' % i], 
            y+1, ws['F%s' % i], ws['G%s' % i])
