# Turn a ChatGPT or Claude Export into Readable Markdown

> Drop in an exported conversations file and get clean Markdown, HTML or plain text — one document per conversation.

This formatter reads the JSON export from ChatGPT or Claude — including ChatGPT's message-graph structure, where turns are stored as linked nodes rather than a list — and renders each conversation as clean Markdown, HTML, plain text or JSONL. Filtering by title, hiding system messages and word counts are all included, and nothing leaves your browser.

## FAQ

### Where do I get the export file?

Both products offer a data export in settings, which arrives by email as a zip. The file you want is conversations.json — paste its contents here.

### Why does ChatGPT's export look so strange?

Because it stores conversations as a graph rather than a list: every message is a node with a parent, so branches created by editing or regenerating a turn are all preserved. This tool walks the nodes and orders them by timestamp to recover a readable transcript.

### Is my conversation history uploaded?

No. The parsing runs entirely in your browser — which is the whole point, given that an export contains every conversation you have ever had.
