It's a handy feature if you have a bunch of error log that you've already captured from Charles and would like to investigate or migrate to the Proxyman app.

How it works

Fortunately, Charles has a built-in command that allows us to convert the CHLS file to the HAR format that Proxyman can understand. Thus, please make sure that you have this app on your machine.

FYI: We can manually convert by executing this command on Terminal

./Applications/Charles.app/Contents/MacOS/Charles convert ~/Desktop/input.chls ~/Desktop/output.har
