Data Dumper is a browser extension for scraping, OSINT reconnaissance, and evidence collection. Open source. Available for Chrome and Firefox.
Two modes of operation. Full Page Scan extracts everything automatically. Manual Selection gives you precise control over what gets captured.
One-click extraction of all entities, links, tables, and images on the page. No element picking or configuration needed.
Click elements directly on the page to define data columns. Rename, reorder, or disable columns before scraping.
Pick the "Next" button and Data Dumper navigates through pages automatically, collecting and deduplicating results.
Scrolls to the bottom of the page repeatedly, waits for new content to load, and collects everything it finds.
Waits for JavaScript-rendered content to settle before extracting. Uses mutation observation to detect when the page is stable.
Attach source URL, timestamp, SHA-256 hash, and user agent to every export. Basic chain of custody for collected data.
Standalone tools for reconnaissance and data collection, independent of the scraper.
Regex-based scanning for emails, phone numbers, URLs, social handles, IP addresses, and cryptocurrency wallets. Includes false-positive filtering.
Collects all links on the page and classifies them as internal, external, mailto, or tel. Sorted by domain for quick analysis.
Finds HTML tables on the page, reports their dimensions, and extracts any of them into structured rows with one click.
Pulls image URLs, alt text, and dimensions. Filter by minimum size or require alt text to narrow results.
Captures the full page HTML and a visible-area screenshot. Timestamped with SHA-256 hash for integrity verification.
Get your data out in whatever format you need.
Comma-separated values with proper quoting and escaping.
XML Spreadsheet format compatible with Excel and LibreOffice. Includes an Evidence sheet when enabled.
Structured XML with row elements and tagged fields.
Raw JSON with evidence metadata. Full scans export all categories as separate keys.
Tab-separated text for pasting directly into spreadsheets.
Load the extension directly from the source code. No store listing required.
