How do I convert HTML to JSON with this tool?

Upload your HTML file or paste the markup into the input field, then click Convert. The tool parses the DOM structure and outputs a JSON object containing all elements, attributes, and text content. You can download the result as a .json file or copy it to clipboard. For multiple files, use the batch upload feature.

Why should I convert HTML to JSON instead of keeping it as HTML?

HTML is designed for visual rendering, while JSON is a lightweight data format ideal for transferring and storing structured data. Converting HTML to JSON strips away presentational tags and leaves clean, machine-readable content that can be consumed by APIs, databases, and JavaScript applications. It also reduces file size and enables easier data manipulation.

What happens to HTML attributes and nested elements during conversion?

The converter retains the full document tree: every tag becomes a node, with attributes like id, class, src, and href preserved as key-value pairs. Nested tags are represented as child objects or arrays, and inline styles are collected into a style object. Text nodes are stored as string values. This ensures no data is lost, making the JSON a faithful representation of the original HTML.
