Accidentally left caps lock on? Need to convert a title to proper case? Writing code and need camelCase variable names? Our free text case converter transforms your text between UPPERCASE, lowercase, Title Case, sentence case, camelCase, PascalCase, snake_case, and more — instantly, with one click. No retyping required.
A text case converter is a tool that changes the capitalization and formatting of text without altering the content itself. Whether you need to fix accidental caps lock, standardize formatting across a document, or convert text to match a specific style guide, a case converter handles it in a single action.
While you can manually retype text in the desired case (or use keyboard shortcuts for basic conversions), a dedicated case converter saves time and eliminates errors — especially when working with large blocks of text or converting between multiple case formats.
Our text case converter supports all major case formats:
You accidentally typed an entire email with caps lock on:
"HEY TEAM, JUST WANTED TO REMIND EVERYONE ABOUT THE MEETING TOMORROW AT 3 PM. PLEASE BRING YOUR LAPTOPS AND THE Q2 REPORTS."
Paste it in, click sentence case, and instantly get:
"Hey team, just wanted to remind everyone about the meeting tomorrow at 3 pm. Please bring your laptops and the Q2 reports."
Problem solved in two seconds.
You're writing JavaScript and need to convert a descriptive phrase into a camelCase variable name:

"userLoginAuthenticationToken"
Click snake_case → "user_login_authentication_token"
"user_login_authentication_token"
Click CONSTANT_CASE → "USER_LOGIN_AUTHENTICATION_TOKEN"
"USER_LOGIN_AUTHENTICATION_TOKEN"
One input, three output formats — perfect for consistent naming conventions across your codebase.
