What is a Case Converter?
A case converter is a tool that transforms text between different capitalization and formatting styles known as "cases." These different cases are commonly used in programming, writing, and various text-based applications to follow specific naming conventions or formatting standards.
How Case Conversion Works
Case conversion involves analyzing text and applying rules about which characters should be uppercase, lowercase, or replaced with special characters. The process may include identifying word boundaries, handling special characters, and applying language-specific rules.
Our tool uses sophisticated string manipulation algorithms to identify word boundaries and apply the appropriate transformations for each case style.

Case Types Explained
UPPERCASE
All characters are converted to uppercase letters. Commonly used for emphasis or for constants in some programming languages.
Example: "THE QUICK BROWN FOX"
lowercase
All characters are converted to lowercase letters. Often used in URLs and for certain coding conventions.
Example: "the quick brown fox"
Title Case
The first character of each word is capitalized. Used for titles, headings, and proper nouns in English.
Example: "The Quick Brown Fox"
camelCase
First word is lowercase, but the first letter of each subsequent word is capitalized, with no spaces. Common in JavaScript and Java.
Example: "theQuickBrownFox"
PascalCase
First letter of each word is capitalized with no spaces. Often used for class and interface names in many programming languages.
Example: "TheQuickBrownFox"
snake_case
All lowercase with words separated by underscores. Popular in Python and database field names.
Example: "the_quick_brown_fox"
kebab-case
All lowercase with words separated by hyphens. Commonly used in URLs, HTML attributes, and CSS classes.
Example: "the-quick-brown-fox"
CONSTANT_CASE
All uppercase with words separated by underscores. Used for constants in programming languages like C, Java, and Python.
Example: "THE_QUICK_BROWN_FOX"
Sentence case
The first letter of each sentence is capitalized, the rest lowercase. This is the standard format for normal written text.
Example: "The quick brown fox. It jumps over the dog."
