hexdump - How to find header signature of xlsb files?

Question

I need to recover some xlsb files using Foremost forensic tool and for that i need to edit config file and enter header bytes.

Using hexdump test.xlsb | head i got this:

0000000 4b50 0403 0014 0006 0008 0000 0021 85d9
0000010 636e 0181 0000 0463 0000 0013 0208 435b
0000020 6e6f 6574 746e 545f 7079 7365 2e5d 6d78
0000030 206c 04a2 2802 00a0 0002 0000 0000 0000
0000040 0000 0000 0000 0000 0000 0000 0000 0000

0000260 e936 5043 a9b5 8972 d895 b333 de33 68cd

and i need to extract value like this xffxd8xffxe1(this is .jpg example header).

Can someone help me with this, since i am not an expert in this field? Thanks in advance.

EDIT

I am answering my own question. Use head --bytes 8 file.extension | hexdump -C
