[New User] Unlocking excel file-failed to parse hashes

Hi,

I need to unlock a few old excel files and I chanced into hashcat by reading this article:
http://pentestcorner.com/cracking-micros...h-hashcat/

Follow through the steps mentioned but kept getting the "Failed to parse hashes using the 'native hashcat' format." error.

Command I use:

hashcat64.exe -a 0 -m 9700 --username -o found.txt hash.txt pass.txt

I have no clue regarding the password or the version of the Excel file is.

Please help. Heres the entire message that I got:
