A CLEAR SCOPE

What it does

Extracts text and safe web links from loaded, top-level HTML tables or matching rows. Handles nested text and simple merged table cells. Keeps data in memory until you download it.

Where it stops

No crawling, automatic pagination, logins, paywall bypass, or proxies. Cross-origin frames, shadow DOM, virtualized off-screen rows, and Chrome-protected pages aren’t supported. Selectors can need updating when a site changes.

Use it thoughtfully

Only extract content you’re authorized to use. Respect site terms, privacy, and applicable rules. Form values and editable fields are excluded. Review sensitive information before sharing any export.

OPTIONAL, ALWAYS

Keep small tools
in everyone’s hands.

Rowmint is free to use. If it saves you time, you can support it with a donation. No wallet connection. No features held back.

Focused, free, and browser-local. Visual extraction is an established category: Octoparse and ParseHub offer both free and paid plans. Rowmint covers a smaller, manual, one-page workflow. It does not replace their hosted automation. Plan links checked October 2026. No affiliation.
