It can, but it can get incredibly slow for large formats. I was using it to reverse engineer some binary game formats but the parser would take a couple of minutes to complete. I rewrote it using struct and that time dropped to a few seconds. Useful for probing an unknown format, but I prefer the 010 editor since it’s more interactive.

Ooh, exciting! I built a parser [1] for AIS messages [2], a quirky ship-to-ship protocol. My lower-level stuff always felt clumsy to me. I'll have to see if this cleans it up.
