Frequently Asked Questions
Find answers to commonly asked questions about text case conversions and data privacy.
What is Sentence case?
Sentence case capitalizes only the first letter of each sentence and leaves all other letters lowercase, matching standard grammar rules.
What is the difference between Proper case and Title case?
Proper case capitalizes the very first letter of every single word in the text, ensuring a uniform capitalized heading structure.
How does Inverse case work?
Inverse case flips the capitalization of every single letter: uppercase characters become lowercase and lowercase characters become uppercase.
