Long cell text is truncated to keep exports practical and avoid oversized CSV files. Cleanup is applied to smart extraction, area picking, template reuse, append-next, and scroll collection results. ## Export Formats - **CSV** is useful for opening in Excel, WPS, Google Sheets, or other spreadsheet tools. - **Excel `.xlsx`** is useful for direct archiving and manual cleanup. - **JSON** is useful for importing into systems, scripts, or automation workflows. Exports use the currently selected fields and edited column names. If duplicate JSON field names exist, the extension appends `_2`, `_3`, and so on to avoid overwriting data. Export filenames automatically include the page title, host name, and current date. ## Batch Collection ### Append Next **Append Next** looks for controls such as: - Next - More - Load more - Show more - Chinese equivalents such as 下一页, 加载更多, 查看更多 It clicks the control, waits for page changes, extracts again, merges the result, and removes duplicates. ### Scroll Collect **Scroll Collect** scrolls down the page several times, waits for lazy-loaded content, extracts again, merges the result, and removes duplicates. These features are useful for search result pages, product feeds, article lists, admin tables, and pages with incremental loading. If a site performs a full page navigation when clicking Next, you may need to wait for the new page to load and open the extension again. The current version works best with load-more buttons, front-end pagination, and lazy-loaded pages. ## Smart Field Naming When the extension has to generate fallback fields such as `Field1` and `Field2`, it examines sample values and may rename them to: - Title - Link - Price - Date - Number - Text Real table headers, user-edited field names, and saved template field names are not overwritten automatically. ## Area Picking 1. Open the extension popup. 2. Click **Pick Area**. 3. Move your mouse on the page. The current target area will be highlighted. 4. Click the table, card, list item, or section you want to extract. 5. Reopen the extension popup to preview the extracted data. 6. If the result looks good, click **Save Template**. ## Templates - Templates are saved per site origin, such as `https://example.com`. - After saving a template, reopening the extension on the same site shows that templates are available. - You can select a template from **Templates** and click **Use Template** to extract with the saved rule. - Templates can be renamed and deleted. - Templates store extraction rules and field settings. They do not store extracted page data.
