 | **Debug websites with evidence** | Connect actions to requests, response bodies, console messages, and page changes. Inspect performance, slow APIs, and suspected duplicate requests; use explicit HTTP rules or request replay to test a hypothesis. |
 | **Choose the right browser** | Name browser instances, bind a task to a specific profile, or pair an agent running on a server with a browser on your computer. |
 | **Review what happened** | Reopen browser-local debugging history, export evidence as JSON, or enable a separate operation audit to review task activity. |
+| **Extract structured data** | Export loaded tables and lists as JSON/CSV with column names, page/frame sources, merged-cell metadata and explicit coverage. See [structured extraction](docs/structured-extraction.md). |

 | **带着证据调试网站** | 把操作与请求、响应正文、控制台和页面变化关联起来，检查性能、慢接口与疑似重复请求，用明确配置的 HTTP 规则或请求重放验证问题。 |
 | **选对浏览器和账号** | 为浏览器实例命名，让任务绑定指定 Profile；也可以让服务器上的 Agent 连接你电脑上的浏览器。 |
 | **回看任务过程** | 重新打开浏览器本地的调试历史、导出 JSON，或单独开启操作审计，查看任务执行记录。 |
+| **提取结构化数据** | 将已加载的表格和列表导出为 JSON/CSV，保留列名、页面/frame 来源、合并单元格信息和完整性标记。见[结构化提取说明](docs/structured-extraction.md)。 |
