Does not support csv

openpyxl doesn't support csv so it needs to be handled separately or simply converted to excel first.

While nothing on github indicates it does support CSV, the blog post does. It would be pretty simple to convert it and save temporary xlsx files to then process.
eg:

import csv
from openpyxl import Workbook

def csv_to_excel(csv_file, excel_file):
    wb = Workbook()
    ws = wb.active
    with open(csv_file, 'r', newline='', encoding='utf-8') as f:
        reader = csv.reader(f)
        for row in reader:
            ws.append(row)
    wb.save(excel_file)

Currently

Commencez dans rvtools_processor.py, au niveau de la commande consolidate, en utilisant l’invocation CSV signalée et l’erreur openpyxl comme point d’entrée. Vérifiez comment les fichiers d’entrée sont actuellement traités et comment la sortie consolidée est créée. Le travail est terminé lorsque les entrées CSV peuvent être consolidées sans l’échec « At least one sheet must be visible ».
