What is the difference between Title Case and Sentence case?

Title Case capitalizes the first letter of all major words (e.g., "The Quick Brown Fox"). Sentence case capitalizes only the first word of the sentence (e.g., "The quick brown fox").

Why is case conversion needed for data?

For data standardization. Databases often require all input to be consistently formatted (e.g., all UPPERCASE) for accurate searching and sorting.

Does it preserve punctuation?

Yes, text formats (lowercase, UPPERCASE, Sentence case, Title Case, alternating, inverse) preserve punctuation and numbers in their original positions. However, programming formats (camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE) automatically remove special characters and punctuation to produce valid identifiers.
