Three small files with the problems real client files have. All data is fictional. Each one opens in the CSV Cleaner in your browser — nothing is uploaded.
Outbound Lead List
Duplicates, a header pasted in twice, mixed phone and date formats, two bad emails.
Open in the CSV Cleaner →CRM Contact Export
The same contact entered twice, names in capitals, an incomplete email, mixed date styles.
Open in the CSV Cleaner →Webinar Sign-Up Sheet
International phone numbers, day-first dates, "Last, First" names, a repeat registration.

Free Tools vs. Human Services
SmartDataAI offers two different things. Please do not mix them up when you talk to clients.
Free browser tools
Run on your own computer. Nothing is uploaded, there is no signup, and nobody at SmartDataAI sees the file. Rule-based, not AI. You — or your client — do the work.
Optional human services
A person cleans the file for a fee. The client chooses to send the file, and it is handled under our Privacy Policy. See the $19 cleaning service or ask for a quote.
Handling Client Data Responsibly
The moment a client sends you a file, you are holding other people's names, emails, and phone numbers. Treat that seriously from your first job.
✓ Use the file only for the job
✓ Never contact anyone listed in it
✓ Keep it in one place, and delete it when you said you would
✓ Do not paste client data into online tools you have not checked — the SmartDataAI tools run locally in your browser, which is why they are safe for this
✓ If a file contains ID numbers, payment details, or health information, stop and talk to the client before you go further
