this function should return the report format, not the report itself

[Rohit1123]

I didn't understand. The function returns report format right - FORMAT_CAPE or FORMAT_UNKNOWN

[mr-tz]

ah sorry, my bad, you are correct, however, there's other locations where cape reports (JSON) are read, see references to json.load, would you change those as well? likely a helper function to load plain or compressed reports would be useful.

[Rohit1123]

@mr-tz, as you suggested, I've created a helper function load_json_from_path that can load both plain and compressed JSON reports, and there are still a few json.loads references, but they are used on strings, not for loading JSON reports (if I'm not wrong)

[mr-tz]

this looks great, please address my comments and add a test e.g. in test_main (test_main_cape_gz or similar)

[mr-tz]

and please add an entry in the changelog so we can recognize your work!

[Rohit1123]

@mr-tz, thanks for the feedback. I've added a test and made an entry in change log.
And lint with ruff is failing because json is imported but unused in capa/loader.py. May I discard import json?

[mr-tz]

yes, please

[mr-tz]

almost ready to go, thank you!

[mr-tz]

amazing, thank you!
