Title: Multi-Source CRM Contact Database Standardization

Project Description: Scrubbing and consolidating messy consumer data lists compiled across multiple event sign-up forms and legacy sheets into a single, clean master file ready for database migration.

What I Did:

Executed deep deduplication across 15,000 rows of raw customer contact text records.

Normalized phone numbers into standard international formats and fixed mismatched date structures.

Cleaned up text columns by fixing typos, capitalizing names, and separating merged text fields.

The Result: Delivered a 100% error-free, tabular dataset ready for smooth CRM integration without any broken entries.
