What Is a Text Case Converter?
A text case converter changes the capitalisation of your text without you retyping a single word. Paste a paragraph that arrived in ALL CAPS and turn it into clean Sentence case, format a heading into Title Case, or generate camelCase and snake_case names for code. It is a daily time-saver for students, content writers, developers and anyone who works with text.

Frequently Asked Questions
Common text case questions
What is Title Case and how is it different from Sentence case?
Title Case capitalises the first letter of every word — used for headlines and titles, e.g. How To Save Money. Sentence case capitalises only the first letter of the sentence, e.g. How to save money. This tool produces both with one click.
Can I convert text to camelCase or snake_case for coding?
Yes. camelCase joins words with no spaces and capitalises each word after the first (myVariableName), while snake_case joins words with underscores in lowercase (my_variable_name). Both are popular naming styles in programming and the tool generates them instantly.
Does converting case change my original text or punctuation?
Only the letter casing changes. Numbers, punctuation, spaces and line breaks stay exactly where they were, so your text keeps its original structure — just with the new capitalisation you selected.
How do I copy the converted text?
Pick a case button to transform the text in place, then click the Copy button to copy the result to your clipboard. You can paste it straight into a document, email, form or code editor.
Is the text case converter free and private?
Yes. It is completely free with no login. All conversion happens inside your browser, so your text is never uploaded anywhere and remains fully private, even offline.
