Link List Cleaner & Checker Prep
Before you audit links, clean the list. This tool normalizes, de-duplicates, and validates a batch of URLs, groups them by domain, and flags malformed or suspicious entries so your crawler only visits real, unique targets.
How to Use
Paste any number of URLs, one per line. The tool resolves duplicates, adds missing schemes, and reports which lines are not valid URLs. Copy the cleaned list or export it as CSV for your crawler.
- De-duplicates by normalized URL and by domain
- Adds a missing http(s) scheme automatically
- Flags malformed entries with the line number
- Groups results by domain with counts
- Export the cleaned list as text or CSV
