What is HTML to JSON
HTML to JSON is a free online converter that serializes an HTML document into a JSON tag tree (tag, attrs, children, text, comment) for inspection — not a general page scraper or JSON-LD extractor.
Paste HTML, Convert, and download .json when you want markup as data for debugging or custom scripts.
How to use HTML to JSON
- Step 1: Add HTML. Paste, Import, Sample, or Fetch URL.
- Step 2: Convert. Build the JSON tag tree in the output pane.
