Case Styles Explained
UPPERCASE
Every letter is capitalised. Used for headings, acronyms, emphasis, and shouting on the internet.
lowercase
Every letter is lowercased. Useful for normalising text before processing it programmatically, or for casual writing styles.
Title Case
The first letter of each word is capitalised. Standard for titles, headings, and proper nouns in English writing.
Sentence case
Only the first letter of each sentence is capitalised. Closest to standard written prose — good for correcting ALL CAPS text that was typed without attention to case.
Common Use Cases
- Copy-pasted text in ALL CAPS: convert to sentence case or title case instantly.
- Heading formatting: ensure consistency across article headings with title case.
- Code and databases: convert to lowercase for consistent string comparisons.
- Social media: UPPERCASE text grabs attention for announcements.
