What is Text Case Converter?

Text Case Converter is a free online tool that transforms text between UPPERCASE, lowercase, Title Case, Sentence case, camelCase, and snake_case instantly. It is useful for normalizing code identifiers, formatting headings, or fixing text pasted from different sources.

How to use

1. Paste or type your text into the input box.
2. Click the desired case conversion button (UPPER, lower, Title, Sentence, camelCase, snake_case).
3. The output appears instantly. Use the Copy button to copy it to your clipboard.

Notes

• camelCase joins words and capitalizes each word after the first (e.g. myVariableName).
• snake_case joins words with underscores and lowercases everything (e.g. my_variable_name).
• Title Case capitalizes the first letter of every word.

FAQ

What is the difference between Title Case and Sentence case?

Title Case capitalizes the first letter of every word. Sentence case only capitalizes the first letter of the first word, treating the rest as normal sentence text.

Can I convert code variable names?

Yes. camelCase and snake_case conversions split text by spaces and punctuation, making them useful for renaming variables or function names.

Does it handle non-English characters?

UPPERCASE and lowercase use the browser's built-in toUpperCase() and toLowerCase(), which support most Unicode characters including accented letters.
