Common Mistakes to Avoid

⚠️

Using uppercase for entire paragraphs

Solution: UPPERCASE TEXT IS HARDER TO READ IN LONG FORM. Use sparingly for headlines and emphasis only.

⚠️

Overusing in professional communication

Solution: In emails and professional documents, uppercase can be perceived as SHOUTING. Use title case instead.

⚠️

Forgetting to adjust punctuation

Solution: Review punctuation after conversion. Some styles prefer no periods after uppercase headings.
