Export

HAEVN can export any conversation — or your entire archive — in two formats: JSON (structured data) and Markdown (human-readable text).

Export formats

JSON

Best for: Backup, programmatic use, re-importing into HAEVN, or piping into other tools.

The JSON export preserves the complete data model: all messages, branches, metadata, timestamps, tool calls, thinking blocks, and binary attachments (base64-encoded). This is the lossless format — everything HAEVN knows about a conversation is in this file.

{
  "id": "abc123",
  "title": "My Conversation",
  "source": "chatgpt",
  "createdAt": "2024-01-15T14:23:00Z",
  "messages": { ... }
}

Markdown

Best for: Reading in note-taking apps (Obsidian, Notion, Bear), sharing with others, or archiving as plain text.

The Markdown export produces a clean, human-readable document with the conversation title, metadata header, and all messages formatted as sections. Code blocks are preserved with language hints. Images are included as inline links or alt-text descriptions.

Works seamlessly with Obsidian’s note linking, Notion’s Markdown import, and any text editor.

Exporting a single conversation

From the Archive: Click Export on any conversation row. A dialog will ask you to choose JSON or Markdown, then the file downloads immediately.

From the Viewer: Click the Export button in the viewer toolbar.

From Search results: Click Export on any search result row.

Exporting multiple conversations

To export a selection of conversations:

1. In the Archive, use the checkboxes to select the conversations you want.
2. Click Export Selected in the toolbar.
3. Choose JSON or Markdown format.
4. HAEVN generates a ZIP file containing one file per conversation, plus any extracted media files.

Exporting your entire archive

Click Export All in the Archive toolbar to download your complete archive as a ZIP file. For large archives, ZIP generation runs in the background — the download will start automatically when it’s ready.

Tip

Backing up your archive: Use Export All to JSON periodically as a backup. The resulting ZIP can be re-imported into HAEVN on another machine using the Import feature.
