What does Crawl extract?

Crawl fetches the public URL you submit and extracts HTML tables, JSON-LD blocks, and qualifying lists into reviewable rows.

What does Chart accept?

Chart reads .xlsx and .xls files in the browser and can also chart the first dataset sent from Crawl.

No. Pages behind logins, heavy bot protection, or unusually large responses may fail or return no structured data.

Chart files stay in your browser. Crawl requests are processed on demand from the URL you submit so the service can fetch and parse the page.

Chart imports stay in your browser. Crawl runs against the public URLs you submit and can fail on login-only, blocked, or unusually large pages.
