How do I convert HTML to JSON using LetsConvert?

Upload your HTML file or paste the HTML code, select "JSON" as the output format, and click "Convert". The tool parses the markup into a structured JSON object, which you can download as a .json file or copy. For batch conversion, upload multiple HTML files and download the JSON outputs as a zip.

Why convert HTML to JSON instead of using it as HTML?

HTML is designed for visual presentation in browsers, while JSON is a data format optimized for storage and programmatic access. Converting HTML to JSON lets you extract content, attributes, and hierarchy into a machine-readable structure that can easily integrate with APIs, databases, or JavaScript applications. This is particularly useful for web scraping, content migration, or headless CMS workflows.

How does the converter handle nested tags and attributes like class, id, or style?

The converter recursively parses the HTML DOM, preserving the parent-child hierarchy. Each tag becomes a JSON object, and attributes such as class, id, href, src, and style are stored as key-value pairs. Text content appears in a "text" field, and data-* attributes are kept intact. The order of attributes remains unchanged, so no structural information is lost.

Is HTML-TO-JSON free to use?

Yes, HTML-TO-JSON on LetsConvert is 100% free with no registration or hidden fees required.
