Online HTML Parser for Free
An HTML parser reads a document and breaks it into the tags, attributes, and text nodes the browser would assemble into a tree.
When you inherit a third-party template and the layout is broken, you need to see how every element nests before you can fix anything. Skimming raw source for an unclosed tag wastes hours, and a stray div buried six levels deep can shift the entire page.
Our HTML Parser builds an interactive tree right next to your code, so the structure is visible at a glance and any unmatched element stands out.
How to Use the HTML Parser
- Paste your markup into the left editor or drop an
.htmlfile onto the workspace. - Watch the DOM tree build on the right with attributes and text nodes already expanded.
- Switch the sidebar to Link Extractor, Meta Extractor, or Attribute Finder for a focused view.
- Use the filter box inside any mode to narrow results to a single tag, URL, or attribute.

Built for Backend Developers, QA Testers, and SEO Auditors
When a stylesheet loads the wrong section, backend developers open the HTML Parser to see exactly where the nesting goes off. QA testers run the same tree to confirm every form field still has the label they expect, and SEO auditors switch to the Meta Extractor to catch a missing Open Graph tag before launch.
The Fastest Way to Read an Unknown Template
The fastest way to learn a strange HTML document is to render it in a browser, open DevTools, and walk every element by hand. Alternatively, our HTML Parser builds the same tree the moment you paste, with attributes and text nodes already in view.
Color-Coded Tags
Headings, links, and structural containers each get their own hue so the tree reads at a glance.
Six Analysis Modes
Switch between DOM tree, plain text, tag count, links, meta, and attributes without leaving the page.
Browser-Only Processing
Your markup never leaves the tab. The DOMParser API does every read locally.
