How to convert text case

Paste your text and pick a case: UPPERCASE, lowercase, Title Case, Sentence case, or toggles like camelCase and capitalised words. The tool rewrites your text instantly so you can copy it straight back into a document, headline, code variable or spreadsheet. It saves retyping when you've pasted in text that's in the wrong case.

Common uses for a case converter

Fix a heading that came in all caps, normalise messy data pasted from a PDF, format names and titles correctly, or convert a label into camelCase for code. Title Case is handy for headlines, while Sentence case reads naturally in body text. The conversion runs entirely in your browser — nothing you paste is uploaded.
