DataSnap

Turn any webpage into structured data. Detect tables and lists, preview, and export to CSV, XLSX, or Markdown.

DataSnap turns any webpage into structured data you can actually use. **What it does** - Detects HTML tables and repeated list/card structures (product listings, job listings, search results) on the page you're viewing - Lets you preview the extracted data before exporting: rename or remove columns, remove rows, trim whitespace, drop empty rows - Exports to CSV, XLSX, or Markdown **Smart Select (Pro)** Can't find what you need automatically? Click on any element on the page and DataSnap finds every similar item for you — perfect for sites with unusual layouts. **Free plan** - CSV export - Up to 3 exports per day - Up to 50 rows per export - Table and repeated-list detection, basic preview cleanup **Pro plan** - Unlimited exports and rows - Smart Select - XLSX and Markdown export - Duplicate-row removal **Privacy first** All detection and extraction happens locally in your browser. Extracted data is never sent anywhere — it only lives in memory long enough to hand off from the page to DataSnap's own Preview tab, and is cleared when you close your browser. DataSnap does not collect analytics or browsing history. The only network activity is checking your Pro subscription status (via ExtensionPay) — which never includes page content or the pages you visit. **Permissions** - `storage`: remember your plan status and daily export count - `activeTab` / `scripting`: read the page you're currently viewing, only when you click "Scan this page" or "Smart Select" — DataSnap has no access to any other tab or page until you ask it to
