A case converter is a tool that changes the capitalisation of text. Instead of retyping or manually editing every letter, you paste your text and click a button to switch between formats like uppercase, lowercase, title case, or programming conventions like camelCase and snake_case in an instant.
Title case capitalises the first letter of each word. It is commonly used in headings, article titles, book names, and blog post titles. For example, "the quick brown fox" becomes "The Quick Brown Fox" in title case.
camelCase joins words together with no spaces, capitalising every word except the
first. It is widely used in JavaScript, Java, and many other programming languages
for naming variables, functions, and object properties — for example,
myVariableName or getUserData.
snake_case replaces spaces with underscores and uses all lowercase letters. It is the
standard naming convention in Python for variables and functions, and is also common
in database column names and file names — for example, user_first_name
or get_user_data.
Uppercase (also called capital letters) refers to the large form of each letter — A, B, C. Lowercase refers to the small form — a, b, c. The terms come from the physical type cases used by early printers, where capital letters were stored in the upper case tray and small letters in the lower case tray.
