What is HTML Parser
HTML Parser is a free online inspector that parses HTML into JSON with document stats, a structure summary, and a tree (capped for very large documents).
Use it when you want counts — elements, images, scripts, links, headings, depth — without spinning up a project or opening DevTools on a full site.
How to use HTML Parser
- Step 1: Add HTML. Paste, Import, Sample, or Fetch URL.
- Step 2: Parse. Run Parse to build stats and a JSON tree.
- Step 3: Review and export. Inspect the JSON, then Copy or Download .json.
