Frequently asked questions
How do I change uppercase to lowercase?
Paste your text and choose lower case. Every letter becomes lowercase, and the result updates as you edit the text.
What is title case?
Title case capitalises the main words of a heading. Short words such as a, and, of and the stay lowercase unless they are the first or last word. Style guides such as AP and Chicago differ on some details, so check a title against your guide if it matters.
What is sentence case?
Sentence case capitalises only the first letter of each sentence, plus the word “I”. Names and acronyms become lowercase, so check those afterwards.
What are camelCase, snake_case and kebab-case?
Naming styles used in code: camelCase (firstName), PascalCase (FirstName), snake_case (first_name), kebab-case (first-name) and CONSTANT_CASE (FIRST_NAME).
How do I change text case in Word, Excel or Google Docs?
In Word, select the text and press Shift+F3 to cycle cases. In Excel, use =LOWER(A1), =UPPER(A1) or =PROPER(A1). In Google Docs, use Format › Text › Capitalization.
Does it work with accented letters and other alphabets?
Yes. Letters such as é, ü and ñ, and alphabets with upper and lower case such as Greek and Cyrillic, are converted correctly.
Is my text saved or uploaded?
No. The conversion happens in your browser, and this page does not store or send your text.
