Clean up a messy lead CSV before it goes into your CRM.
Drop in an export from any lead source. The tool trims and normalises every field, removes duplicates, flags invalid and disposable emails, and gives each lead a score out of 100. It is free, open source and private by design: your CSV is parsed, scored and downloaded entirely inside your browser tab. Your data never leaves your device.

How scoring works
No black box here. The rules are plain and the exact weights sit in js/qualify.js:
| Signal | Points |
|---|---|
| Corporate (non-free) email domain | +40 |
| Valid email syntax | +20 |
| Has a name | +15 |
| Has a company | +15 |
| Has a phone number | +10 |
| Disposable email domain | score set to 0 (Disqualified) |
Buckets: Hot is 70 and above, Warm is 40 to 69, Cold is below 40. A disposable email lands in Disqualified regardless.
