ChatGPT Exporter by GerTex

About

ChatGPT Exporter by GerTex adds a single "Export JSON" button to the ChatGPT interface. Click it, and the full conversation downloads to your computer as a .json file — not just the messages you can see, but the complete conversation tree that ChatGPT's backend stores: every branch, every edit, every regeneration, every tool call, and all associated metadata.

Built by GerTex, LLC — German Engineering In Texas.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
WHAT YOU GET IN THE JSON
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

- Conversation title, creation time, update time, and conversation ID
- Model slug(s) used throughout the conversation
- The full "mapping" tree: every message node with parent/child pointers
- All branches — including ones you regenerated away from or edited over
- Message authors (user, assistant, system, tool), content parts, and per-message metadata
- The current_node pointer marking the leaf of your currently-selected branch
- Moderation results, attachments metadata, and any other fields ChatGPT's backend returns

This is the same payload ChatGPT's own web app uses internally — no trimming, no lossy reformatting.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
WHY RAW JSON?
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

- Archiving — keep a permanent, machine-readable copy of important chats
- Analysis — feed conversations into your own tooling, notebooks, or scripts
- Migration — move context into other LLM clients or self-hosted chat UIs
- Compliance & recordkeeping — preserve the full conversational state, not just the rendered text
- Debugging prompt workflows — inspect regenerations and branches that the ChatGPT UI hides

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
HOW IT WORKS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

1. Open any conversation on chatgpt.com (or chat.openai.com).
2. An "Export JSON" button appears in the header next to Share.
3. Click it — a .json file with the conversation title downloads instantly.

The button only appears when an actual conversation is open. On the new-chat view there's nothing to export, so nothing is shown.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
PRIVACY — THIS IS IMPORTANT
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

- No data collection. No telemetry. No analytics. No tracking.
- No GerTex server is ever contacted. At all.
- The extension only talks to ChatGPT's own domains (chatgpt.com / chat.openai.com) using your existing login session — the exact same API the ChatGPT web app uses.
- Your exported JSON is saved directly to your own Downloads folder. Nothing is uploaded anywhere.
- Minimum permissions: host access to ChatGPT's domains (to inject the button and fetch the conversation). No API permissions are declared at all.

JSON STRUCTURE (HIGH LEVEL)
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

{
  "title": "…",
  "create_time": 1730000000.0,
  "update_time": 1730000000.0,
  "mapping": {
    "<node-uuid>": {
      "id": "<node-uuid>",
      "parent": "<parent-uuid>",
      "children": ["<child-uuid>", …],
      "message": {
        "author": { "role": "user" | "assistant" | "system" | "tool", … },
        "content": { "content_type": "text", "parts": ["…"] },
        "create_time": 1730000000.0,
        "metadata": { "model_slug": "gpt-…", … }
      }
    }
  },
  "current_node": "<node-uuid>",
  "conversation_id": "…",
  …
}

The "mapping" object is the full branch-aware tree. Walk from "current_node" up through "parent" pointers to reconstruct the visible conversation; traverse "children" from the root to see every branch.
