Three text functions. One powerful lesson about data standardization in business.

UPPER. LOWER. PROPER.

Most people learn these in 30 seconds and move on. But the business insight behind them took me much longer to appreciate.

Inconsistent text formatting is one of the most common causes of broken VLOOKUP results, flawed merge operations, and unreliable reports.

"Apple" and "APPLE" are the same product — but Excel treats them as different entities without text case correction.

This is what data quality thinking actually looks like in practice:
→ Identify where inconsistency enters the dataset.
→ Standardize before you analyze.
→ Never assume your source data is clean.

Small formatting errors compound into big analytical mistakes.

The best analysts build systems that catch these issues before they corrupt the output.
