It’s the mini blog to help you migrate files from Charles to Proxyman.

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

How to use

1. Export Charles Session

We can export the current session in two ways:

  • Right-click on the selected requests -> Export Session -> Select chls format -> Save
  • or File menu -> Export Session as… -> Select chls format -> Save

3. Automatically convert

At the first time you’ve used this feature, Proxyman would prompt the warning to make sure you’re aware that Proxyman will use Charles to convert automatically.

4. All done

At this step, Proxyman will find the default Charles app path and trigger the command to convert the file.
