Count headings, links, images, and extract the document title into JSON for quick structural audits.
Quick answer: HTML to JSON Summary
Summarize headings, links, images, and title text into JSON for quick audits without DOM APIs.
Example: Marketing page export → counts 1 H1, 6 H2s, 42 hrefs, 11 imgs, title “Orbital – Analytics”.
Calculations follow the documented formula on this page; rounding and input units can change the last digit-treat outputs as educational estimates unless you reconcile with source systems.
* This is an estimate. Actual amounts may vary slightly based on input assumptions.
Useful when you only have static HTML exports from crawlers or email templates and need a fast structural read.
