Bulk WHOIS Lookup Exporter

WHAT IT DOES

Bulk WHOIS Lookup Exporter solves a common research challenge for domain investors, security professionals, and system administrators: retrieving WHOIS registration details for multiple domains is tedious when done one at a time. This tool lets you enter a list of domain names (comma-separated or line-separated) and performs a WHOIS lookup for each to retrieve registration details including registrar, creation date, expiration date, name servers, and registrant information where available. Results are displayed in a structured scrollable list with key fields extracted and formatted. You can export the complete dataset as CSV for spreadsheet analysis or JSON for programmatic use. A preview shows your domain list before lookup, and progress tracking shows each domain as it's processed. The tool supports multiple TLDs and presents standardized output across different registries, making it easy to compare domain registration data.

WHERE IT RUNS

This extension panel runs directly inside your browser as an overlay on any web page. It works independently of any specific site and requires no additional API keys or permissions beyond the BotGentz extension. The tool performs WHOIS lookups through public APIs, making it usable from any browser session. It supports all domain TLDs and IP addresses.

HOW TO USE

After installing the BotGentz extension and activating Bulk WHOIS Lookup Exporter, click the extension icon in your browser toolbar to open the panel. Enter your domain names in the text area — you can separate them by commas or new lines. For example: "example.com, my-idea.net, test.org" or each on its own line. The preview section shows how many domains you've entered. Choose your export format: CSV for spreadsheet compatibility or JSON for structured data. Click "Lookup Domains" to begin the WHOIS lookups. The tool processes each domain sequentially with a 400ms delay, showing live progress updates. Results appear with color-coded status indicators and show key fields including registrar, creation date, expiration date, name servers, registrant, and admin email. Click "Export Report" to copy the complete dataset to your clipboard in your chosen format. Click "Clear" to reset the panel and start a new list.

TECHNICAL OPERATION — WHOIS Data Retrieval and Parsing

This tool uses a public WHOIS API to retrieve registration data for each domain. When you click "Lookup Domains," the tool sends a request to the WHOIS API for each domain using GM_xmlhttpRequest. The raw WHOIS response is then parsed using a flexible parser that extracts key fields including registrar, creation date, expiration date, name servers, registrant name, and admin email. The parser is designed to handle variations in WHOIS output formats across different registries and TLDs, using case-insensitive matching for common field names. The extracted data is structured into a consistent format for display and export. The tool uses a 400ms delay between requests to avoid rate limiting and API congestion. Results are stored locally and can be exported as CSV with proper field quoting for Excel compatibility, or as structured JSON for programmatic use.

THE PANEL

The extension panel is fully draggable and remembers its position per site session. It snaps to the nearest edge of the browser viewport when dragged within 50 pixels of any side. You can collapse the panel to a compact title bar using the minimize button, preserving your selection state. The panel resizes vertically by dragging the bottom edge. Press the Escape key to close the panel instantly. The preview updates in real-time as you enter domains, and the results section updates as lookups complete.

PLEASE NOTE

This tool requires the free BotGentz extension to function. The script performs WHOIS lookups through public APIs and does not store, transmit, or log any domain data or user activity. All lookups are performed locally from your browser session. The availability of WHOIS data varies by TLD and registrar — some domains may have limited or redacted information due to privacy protection (GDPR, etc.). The tool uses public APIs that may have rate limits; the built-in delay helps prevent this. WHOIS data can change over time; results are accurate at the time of lookup. Always verify critical domain information directly with the registrar before making decisions based on this tool's output. Export formats include CSV and JSON for maximum compatibility with analysis tools.
