Identifying Data Type From Binary File

Using javascript, I want to read data from a file that looks like this:

1003 0000 1b0c 0900 0300 1000 0003 0200
0a00 0302 1102 030c 1b00 1a03 0000 0100
1200 030a 090c 1b00 0307 1000 1003 1400

What data type is this? Is it a collection of 8-bit unsigned integers?

Solution

  • That is hexadecimal. Each one of those 4-digit chunks are the equivalent of 2 bytes or 16 bits.

    As far as what it's supposed to represent, that is completely dependent upon how you choose to interpret it. The data itself does not provide context. For example, you could choose to interpret that as a very large bitmask, a string, etc. You need to figure out what it is supposed to represent before you can actually interpret / do anything useful with it.
