Map complex data structures instantly. Paste raw JSON or XML and extract every unique key and attribute name.
How Our Key Extraction Engine Works
Paste your raw JSON, XML, or YAML data into the input box. Our tool handles everything from small config snippets to massive API response dumps instantly.
Our "Namespace-Aware" engine scans your structure. It identifies JSON property names and XML tags while preserving important colons (like soap:Header).
The extractor automatically strips away brackets, quotes, and equals signs. You get a clean, alphabetized, and deduplicated list of unique keys ready for mapping.
Your sensitive data never leaves your computer. All extraction logic is processed locally in your browser, making it the safest way to handle proprietary API keys or logs.
Go beyond just tag names. Our engine also isolates XML attributes (like id= or class=), giving you a full view of your data's schema.
Copy your clean list to your clipboard with one click or download it as a .txt file to import directly into Excel, SQL, or your favorite code editor.
