从上传的二进制字段读取 xlsx，Odoo 15

Question

I need to get values from already uploaded xlsx field. How can I do it?

This my binary field:

project_documents_mts_l0 = fields.Binary(string='MTS - Teklif')

When i get the Integer value from xlsx file, want to put this field:

field_source_budget_project = fields.Float(string='Proje', default=0, compute="_field_source_budget_project")

Extracted from some code I wrote some months back. You need the xlrd library https://xlrd.readthedocs.io/en/latest/ :

   from xlrd import open_workbook
   import base64

   excel_file = base64.b64decode(self.ms_file)
   wb = open_workbook(file_contents=excel_file)
   sheet = wb.sheets()[0]
   for row_index in range(0, sheet.nrows):
       row = sheet.row(row_index)
       for cell in row:
           print(cell.value)

That will look through every cell in every row in the workbook, printing it. You need to just extract the files you want. My binary file field is self.ms_file in my example.

The xlrd library is pretty easy to use.
