vellum-ai Import ChatGPT conversation history into Vellum so users can keep their conversation context and memory when switching from ChatGPT.
How to guide the user
When a user wants to import their ChatGPT conversations:
- Tell the user how to export. They need to go to ChatGPT Settings > Data controls > Export data. ChatGPT will email them a ZIP file.
- Ask the user to upload the ZIP file. Use whatever file upload tools or skills are available to receive the ZIP.
- Run the import. Once you have the ZIP file path, run:
bun run scripts/parse-export.ts --file "$ZIP_PATH" | assistant conversations import --json
The parse-export.ts script parses the ChatGPT ZIP and converts it to the standard import format. The assistant conversations import command reads the JSON from stdin and creates the conversations.
The command returns JSON:
{ "ok": true, "imported": 12, "skipped": 0, "messages": 347 }
Report the results — how many conversations and messages were imported, and any skipped duplicates.
Notes
- Only ZIP files are accepted (the full export archive from ChatGPT).
- Conversations are deduplicated — re-importing the same file will skip already-imported conversations.
- Only user and assistant messages are imported (system prompts and tool calls are filtered out).
- Original timestamps from ChatGPT are preserved.
- Imported conversations are automatically indexed for memory search.
