Excel TRIM Formula: Professional Data Sanitization

Data imported from external CRM or ERP systems often contains hidden leading or trailing spaces that can cause lookup formulas to fail. The TRIM formula sanitizes these strings by removing all spaces except for single spaces between words, ensuring 100% data fidelity.

How it Works?
