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.

Will Crawl work on every page?

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.

New field note: set export DPI before sharing chart PNGs for print

2026-08-03

Charts that look sharp on screen often appear blurry when printed or embedded in a PDF report. The fix is to set the export DPI before generating the PNG, not after.

We published a hands-on note covering when to use 96 DPI for screen, 150 DPI for internal documents, and 300 DPI for print-ready exports. The article is available in the blog index for all three site languages.
