ChatGPT Conversation Exporter (Tampermonkey)

Export the currently opened ChatGPT conversation from the web UI to Markdown, JSON, TXT, or PDF.

Features

• Floating, collapsible toolbar on the right side of the page.
• One-click export to:
  • Export MD
  • Export JSON
  • Export TXT
  • Export PDF
• Built-in export settings (persisted in localStorage):
  • Include metadata (default: on)
  • Expand citations (default: on)
• PDF export uses a hidden print frame. If printing is blocked, retry export.
• Local-only workflow: no upload to any server.

Install

1. Install Tampermonkey in your browser.
2. Create a new userscript.
3. Paste the content of userscript/chatgpt-exporter.user.js.
4. Open a ChatGPT conversation (https://chatgpt.com/c/...), then use the floating export toolbar.

Usage

1. Open the target conversation page.
2. Click the export button for the format you need.
3. The script downloads the file directly in your browser.
4. For PDF:
   • If print opens normally, choose "Save as PDF".
   • If print is blocked, run Export PDF again.

Export Data Model

JSON export uses this shape:

{
  "source": "chatgpt_web_dom",
  "thread_url": "https://chatgpt.com/c/...",
  "title": "Example",
  "exported_at": "2026-03-26T20:15:00+08:00",
  "messages": [
    {
      "id": "msg_1",
      "role": "user",
      "created_at": "2026-03-26T20:14:00+08:00",
      "content_parts": [
        { "type": "markdown", "text": "Hello" }
      ],
      "citations": [],
      "attachments": []
    }
  ]
}

Notes

• If no parseable message nodes are found, the script shows an explicit warning instead of exporting incomplete content.
• DOM selectors may need updates after ChatGPT UI changes.
