Converting Text Between Letter Cases
Overview
Switching text between UPPERCASE, lowercase, Title Case, and other styles by hand is tedious and error-prone. This converter transforms your text into any case instantly, including sentence case, camelCase, and snake_case, entirely in your browser.
How to Use (Step by Step)
- 1
Paste your text
Enter the text you want to reformat.
- 2
Choose a case style
Pick uppercase, lowercase, title, sentence, camel, or snake case.
- 3
Copy the result
The converted text is ready to copy and use.
How It Works
The tool applies rules for each case style: uppercase and lowercase change every letter; title case capitalizes the first letter of each word; sentence case capitalizes only the first letter of each sentence; camelCase and snake_case reformat for code identifiers. You paste text, pick a style, and copy the result — no manual retyping.
When to Use This
Fixing text typed with caps lock on. Formatting headings into title case. Converting a label into camelCase or snake_case for code.
