Change case without retyping
Switching text between UPPERCASE, lowercase, Title Case, or programming styles like camelCase and snake_case is tedious by hand and easy to get wrong. This converter applies the rule you pick to the whole block at once, so a heading pasted in all caps, a variable name in the wrong style, or a sentence that needs proper capitalisation is fixed in a click.
How to use it
- Paste your text.
- Choose a case: UPPER, lower, Title Case, Sentence case, camelCase, PascalCase, snake_case, or kebab-case.
- Copy the converted result.
Which style to pick
- Title Case for headings and names.
- Sentence case for body text that was shouted in all caps.
- camelCase / snake_case / kebab-case for code identifiers, database columns, and URL slugs respectively.
Questions people ask
Does Title Case know which words to leave lowercase? It capitalises each word simply; for strict editorial style, scan short words like "and" or "of" afterwards.
