Domain Extractor Tool for Text Analysis
The domain extractor identifies and extracts domain names from any text content including URLs, email addresses, and plain domain mentions. Using pattern matching and validation, the tool finds domains regardless of format or context. It automatically removes duplicates, counts occurrences, and provides clean output ready for analysis or further processing. All extraction happens locally in your browser ensuring privacy for sensitive data like customer email lists or internal logs.
Extracting Domains from Different Formats
Domains appear in multiple formats across different types of content. Full URLs include protocol, domain, and path (https://www.example.com/page). Email addresses embed domains after the @ symbol ([email protected]). Naked domains appear without protocol or path (example.com or www.example.com). The extractor handles all formats intelligently, parsing each to extract just the domain portion. It recognizes hundreds of top-level domains (TLDs) including country codes, generic TLDs, and new gTLDs ensuring comprehensive coverage.
Subdomain Handling and Root Domain Extraction
Subdomains add complexity to domain extraction. Deciding whether to keep or remove subdomains depends on your use case. SEO analysis might need full domains with subdomains (www.example.com, blog.example.com) to track specific properties. Email domain analysis typically wants root domains only (example.com) for organization-level grouping. The tool provides options for both approaches, letting you extract exactly what you need. Root domain extraction intelligently handles multi-level TLDs like co.uk or com.au to preserve accurate domain boundaries.
