UPPER/lower tips

💻

UPPERCASE is used for constants in programming, acronyms, and emphasis. Convert back to normal case after you're done.

📊

Cleaning CSV data? Convert all names or addresses to consistent case in one click.

📝

ALL CAPS text feels like shouting. Use lowercase for casual writing and sentence case for formal text.

💡

Combine with other converters — lowercase first, then apply title case for a clean headline.
