# Charles Proxy Converter

## 1. What's it?

Proxyman is capable of converting and reading the `chls` files from Charles Proxy app to `har` format that Proxyman can understand.

You can manually convert the files from the File menu -> Convert -> `chls` to `har`

## 2. How does it work?

In general, Proxyman uses [Convert CLI from Charles Proxy](https://www.charlesproxy.com/documentation/tools/command-line-tools/) to convert .chls to .har, which Proxyman can understand.

1. As soon as you open `chls` file, Proxyman tries to find the Charles Proxy app, which has a bundle ID is

   `com.xk72.Charles`
2. Convert by using the convert command

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

```

3\. The output is `har` formatted in your Desktop directory

## 3. How to use?

There are several ways to open `chls` files:

* Open the `chls` file directly (Double-Click on the file, or Open With from Finder app)
* Drag and drop the file to the Proxyman app
* File -> Open and select `chls` files
