Common Questions

Which case is best for URLs?

Use lowercase kebab-case (e.g., my-blog-post) for URLs. This is the web standard and is most readable for both humans and search engines.

Should I use Title Case for all headings?

It depends on your style guide. AP style uses title case for headings, while sentence case is increasingly popular for its readability, especially in web content.

Can I convert case in Excel?

Yes! Use =UPPER(A1) for uppercase, =LOWER(A1) for lowercase, and =PROPER(A1) for title case. However, Excel doesn't support camelCase or snake_case natively.
