How do I control what data is extracted?
Chat4Data uses a 4-step confirmation flow so you stay in control at every stage:1
Target Area
Chat4Data identifies the main content region on the page. You can redirect it: “Focus on the product grid, not the featured section.”
2
Fields
The AI proposes fields to extract (e.g., name, price, rating). Add or remove any: “Also grab the seller name” or “Skip the description.”
3
Data Volume
Confirm how many records you want — a page’s worth, a specific number, or everything available.
4
Final Check
Review a sample before the full run starts. If something’s off, just say so in plain English.
How do I modify fields mid-extraction?
Just type your change in natural language at any point:Can Chat4Data filter out ads and navigation?
Yes — the AI automatically focuses on meaningful content and ignores sidebars, navigation bars, and ad blocks. You can also give explicit instructions like:"Ignore the sidebar""Only get data from the main listings area"
