WHY USE IT
A focused tool for reliable HTML work

Copy or download the parsed tree as JSON for debugging, teaching or documentation.
HOW IT WORKS
Three quick steps
- 01Paste HTML
Add a complete page or a smaller component fragment.
- 02Build the tree
Parse the source with the browser’s HTML parser and expand the nodes you want to inspect.
- 03Export if needed
Copy or download the generated DOM representation as JSON.
COMMON QUESTIONS
DOM Tree Viewer FAQ
Is the DOM tree identical to the original source?
The browser parser may insert implied elements or repair malformed markup, so the tree represents the parsed DOM rather than a character-for-character copy of the input.
Does the viewer run scripts in my HTML?
No. It parses the source as data and never executes scripts from it.
How large can the visualized tree be?
The interface limits output to the first 1,500 meaningful nodes so unusually large documents remain responsive.
