Frequently Asked Questions
Where do I get conversations.json?
In ChatGPT, go to Settings → Data controls → Export data and confirm the email link; the zip contains conversations.json. Claude offers a similar "Export data" option in its privacy settings.
Why is the ChatGPT export format so strange?
ChatGPT stores each conversation as a tree (mapping of node IDs with parent/children pointers) to support branching and edits. This viewer walks the tree in order and extracts the main message flow for you.
Does this work with Claude exports?
Yes. The viewer auto-detects Claude conversations (uuid/name/chat_messages with human and assistant senders) as well as the ChatGPT mapping format.
Is my chat history uploaded anywhere?
No. Parsing happens entirely in your browser with JavaScript — the export content never leaves your device, and there is no account or server involved.
