I am looking to view the contents of an .iwa file in my Apple Numbers project. It seems like the format is a protobuf wrapped in snappy. I was wondering if there was a relatively simple/crude way to view the text contents of the data. I tried with a basic hexdump but it just gives me some gibberish, probably because of the snappy encoding.

What might be a way to view this data? As an example, here is a sample file: https://drive.google.com/file/d/1-AZdpuoshfmpjxMfi7ARKhneeUNmW9Xx/view?usp=sharing

  • often there is some ISO spec describing all the minute details of an encoding ... I once had to ruffle through hundreds of pages of such a spec to write code to parse a compressed binary http-live-streaming feed on an embedded project – Scott Stensland Sep 17 '21 at 12:28
