How this page handles your files or data
This tool runs in your browser. Your files or pasted data stay in this tab for the main action and are not uploaded to Wanglitou servers.
Use the visible Remove, Reset, Clear, or Delete local result controls to empty the current page state before leaving shared devices. Wanglitou focuses on practical SEO, creator, and document workflows: clear inputs, reusable output, and honest limits instead of vague claims.
Why use this here
Different from a basic sorter
Extracts numbers from text labels such as item-7 or score: 42.
Shows count, invalid lines, min, max, mean, and median.
Copy a small audit note when you need to explain how a list was cleaned.
