Fix json process

[hanhyalex123]

As you can see, the current JSON string returned by ChatGPT contains many "\n" characters, some of which are inside the "content" field and some are outside. The previous solution was to remove all "\n" characters, which caused the loss of all line breaks and structure when storing the data as a file, especially for code. Therefore, my approach is to first extract the content from the JSON string, remove all "\n" characters, and then put it back to its original position.
