I can view my packet data as a hex dump, but I need to decipher the individual bits and rather than manually doing the conversions I was wondering if there was a way to translate the data into a binary format.
If you want the raw frame data in binary form, you could read the capture file yourself.
If it's a pcap file, you could write a program using libpcap to do that. (See tcpdump's source as an example.)
If it's a pcapng file, newer versions of libpcap can read those, as long as they fit within the constraints of the current pcap API, i.e. all interfaces in the file must have the same link-layer header type and snapshot length.
If it's neither pcap nor pcapng, or it's in another format, you could try getting the Wireshark source, building it, and then adding your own program using Wireshark's libwiretap library to read it. (See the editcap source as an example.)
You're talking about binary format, but also a text file. From this combination I assume that you mean a file with the text representation of the individual bits rather than bytes.
Currently you can only display the packet bytes as bits, but not save it as such. So what you can do is take the current possibility of hexdump export and script a postprocessing step to convert from hex to bits.

So what you want is a text file that looks like, for example:
I.e., it's a text file, displaying, as text, a hex dump?
No I can do that easily. Was wondering if there was a way through wireshark to export the hex dump to a file and then converts the hex data into individual bits so I can validate my data that way instead of manually converting it myself (which would take forever).
What do you mean by "individual bits"?
A text file containing a sequence of characters that are "0" and "1"?
Or a non-text file that's the raw binary bytes (which means the "individual bits" are in chunks of 8)?
What I mean by invididual bits is the data formatted into binary versus a hex form. I already wrote a program to convert the hex dump from a bin to a text file printed with the data converted from hex to binary
If you mean "a binary dump as text", that's "a text file containing a sequence of characters that are "0" and "1"" - that would be "formatted into binary versus hex".
Is that what you want?
