About this tool

Fixing text case by hand is tedious — especially long headings typed in caps lock or variable names that need a different convention. This converter transforms any text into uppercase, lowercase, Title Case, camelCase or snake_case with one click, which makes it handy for writers, editors and developers alike.

How to use

  1. 1 Paste your text into the box.
  2. 2 Click the case style you need: UPPER, lower, Title, camelCase or snake_case.
  3. 3 Copy the converted result.

Why use this tool

  • Five case styles in one tool, including developer formats.
  • Fixes accidental caps-lock text in one click.
  • Instant conversion with no length limit.

Frequently asked questions

What is Title Case?

Title Case capitalizes the first letter of each word — commonly used for headlines and headings.

When is camelCase or snake_case used?

They are programming naming conventions: camelCase (myVariableName) is common in JavaScript and Java, snake_case (my_variable_name) in Python and databases.

Does the tool change my punctuation?

No — only letter casing changes; punctuation, numbers and spacing stay exactly as entered.
