ChatGPT: Conversation Log Export Extension
This is an extension that exports (downloads) OpenAI's ChatGPT conversation logs in JSON format.

to download the conversation in JSON format.
The JSON data is unprocessed. It still contains various information such as chat text, date, and time, so please filter it as appropriate and use it.
