How to open a password protected excel file using python?

Solution 1:

I don't think that named parameters work in this case. So you'd have to do something like:

xlwb = xlApp.Workbooks.Open(filename, False, True, None, password)

See http://msdn.microsoft.com/en-us/library/office/ff194819.aspx for details on the Workbooks.Open method.

Solution 2:

I recently discovered a Python library that makes this task simple.

It does not require Excel to be installed and, because it's pure Python, it's cross-platform too!

msoffcrypto-tool supports password-protected (encrypted) Microsoft Office documents, including the older XLS binary file format.

• Install msoffcrypto-tool:

   pip install msoffcrypto-tool
  

• You could create an unencrypted version of the workbook from the command line:

  msoffcrypto-tool Myfile.xlsx Myfile-decrypted.xlsx -p "caa team"
  

• Or, you could use msoffcrypto-tool as a library. While you could write an unencrypted version to disk like above, you may prefer to create an decrypted in-memory file and pass this to your Python Excel library (openpyxl, xlrd, etc.).

  import io
  
  import msoffcrypto
  import openpyxl
  
  
  decrypted_workbook = io.BytesIO()
  
  with open('Myfile.xlsx', 'rb') as file:
      office_file = msoffcrypto.OfficeFile(file)
      office_file.load_key(password='caa team')
      office_file.decrypt(decrypted_workbook)
  
  # `filename` can also be a file-like object.
  workbook = openpyxl.load_workbook(filename=decrypted_workbook)
  

Solution 3:

If your file size is small, you can probably save that as ".csv". and then read

It worked for me :)
