Add to ChromeExport Claude conversation as JSON for scripts
To export Claude conversation as JSON, install Download Claude conversations, open the thread on claude.ai, click the orange button, choose JSON, then click Export. Chrome saves a per-chat file with the message tree. That file is not Anthropic’s account ZIP. JSON export is unlimited and free, with no account; Pro ($3.99 a month or $26.99 a year) only matters for bulk and PDF.
How do I export Claude conversation as JSON?
Open the conversation on claude.ai in Chrome, click the orange button beside the message box, choose JSON, then click Export. Download Claude conversations writes the file locally.

- Install Download Claude conversations from the Chrome Web Store.
- Reload claude.ai and open a real conversation URL, not the empty composer home.
- Click the orange download button to the right of the message box.

- Click Export. Chrome downloads the JSON through the browser download API. Or click Copy to put the JSON on the clipboard.
No sign-in is needed to export Claude conversation as JSON. Single-chat JSON exports are unlimited, anonymous, and send nothing to our servers. Google sign-in is asked only for PDF and bulk Export All. Mechanics: how it works.
If the orange button is missing, you are not on a conversation URL, the tab needs a reload, or the extension is hidden in the Chrome puzzle menu. Pin Download Claude conversations, then refresh claude.ai. The content script never injects in Claude Desktop or the Claude Code terminal.
One thread vs many files. The orange button exports the open chat as JSON. For many JSON files, open View and Download All Conversations and run Export All with JSON selected: one ZIP, 3 chats a day on the free plan — see bulk Export All.
When should I export Claude conversation as JSON?
Export Claude conversation as JSON when a script, indexer, or diff tool will read the file. The JSON is built for the message tree, not for reading in Obsidian. If you want headings and fenced code for humans, pick Markdown instead. For a spreadsheet, pick CSV: one row per message.
Copy-paste from claude.ai loses sender structure. Print keeps webpage chrome. When you export Claude conversation as JSON, Download Claude conversations keeps turns, senders, and optional thinking as data, not as a flattened paragraph. That is why developers pick JSON over plain text.
We write JSON from the claude.ai tree already on the page — sender, content blocks, timestamps, model metadata — without uploading the thread. That JSON is not Anthropic’s account ZIP. In version 1.16.2 it is one of seven formats, next to PDF and CSV, and it is free with no account.
People also search Claude Chat Downloader and Claude Conversation Downloader for the same listing. Export Claude conversation as JSON is that orange button, not a second product. Legal pages may still say Claude Exporter.
What is in a Claude conversation JSON export?
A Claude conversation JSON export mirrors the message tree on claude.ai: sender, content blocks, timestamps, and model metadata. Thinking blocks, web search sources, tool / MCP steps, and artifacts are included when those options are on: Thinking is a checkbox in the export panel, and tools and sources are switched on in Settings. Sender filter can limit the file to all messages, human only, or assistant only. Nothing is flattened into Markdown first.
Artifact layout in version 1.16.2 is Original, Inline, Nested, or Flat. Those layouts change how artifact content is nested in the JSON, the same four options used for Markdown and XML. Full list: Chrome extension features. For pages instead of data, export PDF.
| Piece | In the JSON? |
|---|---|
| Message tree (turns, sender) | Yes |
| Content blocks | Yes |
| Timestamps and model metadata | Yes, when Metadata is on |
| Thinking blocks | If the Thinking toggle is on |
| Artifacts | Yes, in the layout you picked |
| Web search sources, tool / MCP steps | If you turn them on |
| Account-wide ZIP wrapper | No — that is Anthropic Export data |
If the thread is long, scroll until claude.ai has loaded earlier messages before you export Claude conversation as JSON. The extension can only serialize what the page has rendered. A half-loaded DOM produces a truncated JSON file.
Claude conversation JSON vs Anthropic Export data?
Both are JSON, but not the same shape or scope. Anthropic Settings → Privacy → Export data emails one ZIP of the whole account after a wait. When you export Claude conversation as JSON, you get one thread immediately in Chrome. Use the ZIP for backup.
| Method | Scope | When the file arrives |
|---|---|---|
| Download Claude conversations JSON | This chat or a bulk selection | Immediately via Chrome download |
| Settings → Privacy → Export data | Entire account | Email link that expires |
| Download Claude conversations PDF | This chat as pages | Immediately, but it is PDF, not JSON |
You cannot pick Markdown inside Anthropic’s ZIP request. You also cannot treat this extension’s JSON as a drop-in for that ZIP schema. Format hub: Claude chat export formats. PDF is for reading, not a JSON export.
Download Claude conversations is not affiliated with Anthropic, PBC. The content script uses the session you already opened on claude.ai. It does not log into Anthropic with separate credentials. Follow Anthropic’s rules for your account.
Can I bulk export Claude conversation as JSON?
Yes. Open View and Download All Conversations, set Chat format to JSON, filter the table, then click Export All. Chrome saves one ZIP with one JSON file per chat. On the free plan that is 3 chats a day with Google sign-in, shared with PDF. Pro at $3.99 a month or $26.99 a year removes that cap for bulk JSON.
The Dashboard lists claude.ai history with search by name, filters All conversations, New, Updated, and Previously exported, Chat and Cowork tabs, and project search. New means not yet exported with Download Claude conversations. Previously exported tracks chats you already saved. Export All is one ZIP of per-chat JSON files, not a mixed-format archive.
The daily limit is per account. Three chats a day on the free plan, shared with PDF. If you select 40 conversations with 3 left, the whole batch is blocked, not cut short. Select fewer or use Pro. Single JSON exports from the orange button stay unlimited.
You can diff two JSON exports of the same claude.ai thread taken at different times the way you would diff any JSON file. Each export is self-contained. A second Export All of the same chats counts every chat again.
Does JSON Claude conversation export need Pro?
No. Single-chat JSON export is free and unlimited, with no account and no counter — same as Markdown, text, XML, CSV, and PNG. Only PDF and bulk Export All have a free limit: 3 a day with Google sign-in. Pro is $3.99 a month or $26.99 a year through Paddle. Download Claude conversations does not charge extra to export Claude conversation as JSON.
Bulk JSON is where the limit shows up. Each chat in an Export All ZIP uses one of the 3 a day, and the count resets at midnight UTC. Pro removes it and restores on a new computer from the same Google account. Paddle is merchant of record; this team never sees card numbers.
The extension runs only on claude.ai in Chrome. Claude Desktop and the Claude Code terminal do not get a JSON button; Claude Code on the web (claude.ai/code) runs on claude.ai, so it exports like any chat. Terminal Claude Code’s /export or JSONL on disk is a different path. Version 1.16.2, September 2026, still does not write Word or Notion.
