I have done before with a tool that is installed with Wireshark call text2pcap.exe. Below are some sites that help in the conversion and have some notes about running your debugs to capture what you are looking for in the router.
Hope this helps, it is still a tedious process.
I agree that the method included as a feature in R10 firmware is the easier option. This feature is described in the document Configuring Packet Capture in AOS.
