Query Parameter Extractor
Extract and analyze query parameters from URLs. Support for multiple URLs and various output formats including JSON, table, and list formats.
Query parameters (also known as URL parameters or GET parameters) are key-value pairs that appear after the question mark (?) in a URL. They are used to pass data to web applications and are commonly used for search queries, pagination, filtering, and tracking.
This tool extracts all query parameters from URLs and presents them in various formats for easy analysis. It supports multiple URLs at once and handles invalid URLs gracefully by reporting errors.
Output Formats:
- List: Human-readable format that groups parameters by URL. Easy to read and understand at a glance. (Default format)
- JSON: Structured format with URL, parameters object, and parameter count. Ideal for programmatic processing and data analysis.
- Table (TSV): Tab-separated values format with columns for URL, Parameter, and Value. Perfect for importing into spreadsheet applications.
Common Use Cases:
- SEO Analysis: Analyze URL parameters for search engine optimization and tracking.
- Data Migration: Extract parameters when migrating between different systems or platforms.
- Analytics: Understand what parameters are being used across your website or application.
- Debugging: Quickly see all parameters in complex URLs during development and testing.
- API Documentation: Document the parameters used in API endpoints and web services.
What are query parameters?
Query parameters are key-value pairs that appear after the question mark (?) in a URL. They are separated by ampersands (&) and are used to pass data to web applications. For example, in "https://example.com?search=query&page=1", "search" and "page" are parameters.
Can I extract parameters from multiple URLs?
Yes! Simply enter each URL on a separate line in the input field. The tool will process all URLs and extract parameters from each one, clearly organizing the results by URL.
What happens if a URL has no parameters?
URLs without query parameters will be processed normally and the results will indicate that no parameters were found. This helps you identify which URLs in your list don't contain parameters.
How are invalid URLs handled?
Invalid URLs are flagged with an error message in the results. The tool will continue processing other valid URLs in your list, so one invalid URL won't stop the entire extraction process.
Which output format should I choose?
The List format (default) is best for quick review and human reading. Choose JSON for programmatic use or data analysis, and Table (TSV) for importing into spreadsheets like Excel or Google Sheets.
