1. Natural language data extraction

The core function of Chat4Data is to extract web page data through natural language. Users enter commands such as "extract product name and price" or "get all contact information" into the extension interface, and the AI automatically analyzes the structure of the web page and identifies the relevant data fields. The steps are as follows:

• Open the target web page (e.g. the product listing page of an e-commerce platform).
• Click on the Chat4Data icon to bring up a dialog box.
• Enter specific requirements in the dialog box, such as "Extract product title, price and image links".

• In the dialog box, enter "Grab product names and prices from all pages".
• AI automatically detects paging links or scroll loading mechanisms to extract data page by page.
• Once the extraction is complete, the data is consolidated into a single dataset, which is displayed in the interface.
• Users can preview data to ensure completeness.

3. Data field adjustments

Users can dynamically adjust the extraction fields through natural language. Example:

• Add Field: Enter "Add a field for the number of comments" and the AI will reanalyze the page and add the field.
• Delete Field: Enter "Delete Scoring Field" and the AI will remove the specified field.
• Fix Extraction: If the results are inaccurate, enter "Reanalyze this page" and AI will optimize the extraction logic.
