Frequently Asked Questions
+What is a text case converter?
A text case converter transforms text between different capitalisation styles — UPPERCASE, lowercase, Title Case, camelCase, snake_case, and more. It saves time when reformatting headings, cleaning up copied content, or converting variable names between programming conventions.
+How do I convert uppercase to lowercase?
Paste or type your uppercase text into the input box above. The "lowercase" card updates instantly with the converted result. Click the copy button on that card to copy it to your clipboard.
+What is the difference between camelCase and PascalCase?
Both join words without spaces. camelCase starts with a lowercase letter (e.g. "myVariableName"), while PascalCase (also called UpperCamelCase) starts with an uppercase letter (e.g. "MyVariableName"). camelCase is common in JavaScript variables; PascalCase is used for class names and React components.
+What is snake_case used for?
snake_case uses underscores between words and is common in Python variables, database column names, and file names (e.g. "user_first_name"). CONSTANT_CASE is the same pattern in all caps, typically used for constants and environment variables.
+Is Title Case the same as Sentence case?
No. Title Case capitalises the first letter of every word (e.g. "The Quick Brown Fox"). Sentence case only capitalises the first word of each sentence (e.g. "The quick brown fox"). Sentence case is closer to normal prose writing; Title Case is used for headings.
+What does kebab-case mean and when is it used?
kebab-case uses hyphens between lowercase words (e.g. "my-component-name"). The name comes from the words being "skewered" on hyphens like a kebab. It is the standard for HTML attributes, CSS class names, URL slugs, and file names in many web projects.
