# Convert ChatGPT conversations into markdown
# source: https://dev.to/gavi/convert-chatgpt-conversations-to-obsidian-markdown-format-p61

# Improvements (tried to match original coding conventions)
# 2023.08.10: Fix bug accessing 'parts' in node['message']['content']['parts']
# 2024.01.06: Updated get_conversation to handle non-string content parts, i.e. images (which are not currently included in the ChatGPT exports)
# 2024.01.20: Added link to conversation in ChatGTP using conversation_id, and also set time stamps correctly, esp. on macOS
