How to use the result
- Domains match better than names. 'Acme' matches hundreds of companies; acme-analytics.com matches one.
- Check subdomains by hand. Regional sites like uk.company.com are kept as they are; decide whether they're separate accounts.
- Remove customers and open opportunities before uploading to acquisition campaigns.

Questions
Straight answers.
Does this find company names for domains?
No. It only cleans what you give it, offline. Use an enrichment tool if you need names, size and industry.
Is my list uploaded?
No. Cleaning runs entirely in your browser.
Why are some rows 'not a domain'?
Header names, company names without a domain and malformed values can't be turned into a domain. The tool shows a few examples.
Can I upload the result to LinkedIn?
Yes, but the LinkedIn company list formatter adds the exact headers LinkedIn expects and keeps names and countries.
