FAQ

What is the Free Web Data Extraction Tool?

This tool lets you extract structured data from any public webpage using CSS selectors. Enter a URL and optionally define selectors to pull specific content — headings, links, prices, images, or any other element — into clean, structured output.

What are CSS selectors and how do I use them?

CSS selectors identify elements on a page. Examples:

  • h1 — selects all H1 headings
  • a.nav-link — selects anchor tags with class nav-link
  • #price — selects the element with id price
  • article p — selects paragraphs inside an article

Use the selectors builder in Advanced Options to add named selectors with a chosen type (text or attribute).

What is the difference between "text" and "attr" types?

The "text" type extracts the inner text of a matched element. The "attr" type extracts the value of a specific HTML attribute — for example, extracting the "href" from anchor tags or the "src" from images.

What does "Multiple results" mean?

When enabled, all elements matching your CSS selector are returned as an array. When disabled, only the first matched element is returned. Useful when extracting all links on a page vs. just the first one.

What is the HTML Elements field?

The HTML Elements field specifies which tags are used to build the "Extracted Text" output — a plain-text concatenation of all matching tag contents. The default is "title,h1,h2,h3,h4,h5,p". You can customize it to any comma-separated list of HTML tags.
