The sentence case converter transforms your text so that only the first letter of each sentence is capitalized, while the rest remains in lowercase. This is the standard format for most written content, including paragraphs, articles, and essays.
Example: “This is an example of sentence case. It looks natural and easy to read.”
The lower case converter changes all letters in your text to lowercase. This is useful for creating email addresses, usernames, URLs, or when you need uniformly lowercase text for programming or data processing.
Example: “this is all in lower case letters.”
The upper case converter transforms all letters to capitals. This is commonly used for headings, acronyms, emphasis, or when you need to make text stand out. It's also frequently used in programming for constants and environment variables.
Example: “THIS IS ALL IN UPPER CASE LETTERS.”
Title case capitalizes the first letter of each word, following standard title formatting rules. This is the preferred format for book titles, article headlines, section headers, and any formal titles.
Example: “This Is An Example Of Title Case Formatting.”
The camelCase converter creates text where the first word is lowercase and subsequent words begin with uppercase letters, with no spaces. This is widely used in programming for variable names, function names, and method names in languages like JavaScript, Java, and C++.
Example: “thisIsAnExampleOfCamelCase”
PascalCase is similar to camelCase but capitalizes the first letter as well. It's commonly used for class names in object-oriented programming, component names in React, and type names in TypeScript.
Example: “ThisIsAnExampleOfPascalCase”
The snake_case converter replaces spaces with underscores and converts everything to lowercase. This naming convention is popular in Python, Ruby, and database column names. It's highly readable and widely adopted in the programming community.
Example: “this_is_an_example_of_snake_case”
The kebab-case converter replaces spaces with hyphens and converts everything to lowercase. This format is commonly used in URLs, CSS class names, and file names. It's SEO-friendly and easy to read in web addresses.
Example: “this-is-an-example-of-kebab-case”
The alternating case converter creates a pattern where letters alternate between lowercase and uppercase. This fun format is often used in memes, social media posts, or to convey sarcasm. It's purely stylistic and not used in formal writing.
Example: “tHiS Is aN ExAmPlE Of aLtErNaTiNg cAsE.”
This function removes all spaces from your text, creating a continuous string of characters. Useful for creating hashtags, processing data, or generating compact identifiers.
Example: “ThisIsTextWithoutAnySpaces”
This function cleans up your text by removing extra spaces, leaving only single spaces between words. Perfect for cleaning up copied text or formatting data that has irregular spacing.
Example: “This text has proper spacing between words”
The reverse text function flips your text backwards, reversing the order of all characters. This can be used for creative effects, puzzles, or encoding simple messages.
Example: “txet desrever si sihT”
