How to transform an Excel to CSV using Python (pandas)

I need help in transforming an EXCEL file (which may have 1 or many sheets) into a CSV file. I was asked to read a Python file (first time I use Python and Pandas) which is in another server to do this request. Searching in the web I found and modified this code:

import pandas as pd
read_file = pd.read_excel (r"/data/IRIS/mgr/PCICODE/ExcelReading/ExcelFiles/Probanding.xls")
read_file.to_csv (r"/data/IRIS/mgr/PCICODE/ExcelReading/CSVFiles2/testFile.csv", index = None, header=True, encoding="utf-8-sig" , sep = ';')

This code does the job, but it does not work properly when the EXCEL file has 2 or more sheets, since I need that if the EXCEL has sheets, every sheet must be in a different EXCEL file, and the code I am using right now just takes the first sheet and discard the rest. I looked for other options and found this code:

import pandas as pd

str_InputFilePath =  input('Name and Path of Excel: ')
str_path = str_InputFilePath.split('/')
int_name = len(str_path)
str_file = str_path[int_ame-1].split('.')
str_shortName = str_file[0]
str_OutputFilePath =  input('Output Path: ')

la  = pd.read_excel(str_InputFilePath, sheet_name=None) 
counter = 0    
for name, sheet  in la.items():
    FileReading  = pd.read_excel(str_InputFilePath, sheet_name=(name)) 
    
    FileReading.to_csv(str_OutputFilePath + str(counter+1) + str_shortName + ".csv", encoding='UTF-32BE', index = None, header=False, sep = ';')
    counter = counter + 1

I tested this last code locally and worked. It takes every sheet from Excel file and creates a CSV file for every single sheet, but the Python file I need to use is in another "server" and I can't send it any Input. So I would really appreciate your help trying to merge these codes. Thank you for your time and guidance!!
