Frequently Asked Questions
What is the difference between camelCase and snake_case?
camelCase capitalization removes spaces and capitalizes the first letter of each word except the first (e.g. `myVariableName`). snake_case replaces spaces with underscores and writes everything in lowercase (e.g. `my_variable_name`).
How does Sentence Case conversion work?
Sentence Case converts the first character of each sentence to uppercase and writes the rest in lowercase.
Does this tool support special characters and accents?
Yes. The converter handles standard UTF-8 characters and accents (like é, ü, ñ) correctly during case conversions.
