Every case style explained
- Sentence case: Capitalizes the first letter of each sentence and lowercases the rest. It also fixes a lone “i” to “I”. The best fix for text typed with Caps Lock on.
- lowercase: Every letter small. Handy for email addresses, hashtags and tidying pasted text.
- UPPERCASE: Every letter capital. Use it sparingly; whole sentences in capitals read as shouting.
- Title Case: Capitalizes the main words of a headline and keeps short words like “a”, “and”, “of” and “the” lowercase, unless they start or end the title.
- Capitalize Each Word: Every word starts with a capital, including short words. Common for names and product lists.
- aLtErNaTiNg and InVeRsE: Playful styles for memes and social posts.
- camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE: Programming styles. They remove spaces and punctuation and join the words, for example
user_first_nameoruser-first-name.
Uppercase to lowercase in Word, Google Docs and Excel
If you only need a quick change inside a document, the apps you already use can do it too:
- Microsoft Word: select the text and press Shift+F3 to cycle between lowercase, UPPERCASE and Capitalize Each Word. More time-savers are in our list of all Microsoft Word shortcuts.
- Google Docs: select the text, then choose Format > Text > Capitalization.
- Excel and Google Sheets: use the formulas
=UPPER(A1),=LOWER(A1)or=PROPER(A1).
The converter above is faster when the text comes from somewhere else, such as an email, a PDF or a web page, and it offers styles the apps don’t, such as Title Case with short words kept lowercase and the programming cases.
Title case rules in brief
Style guides such as AP and Chicago differ on small details, but they agree on the basics, which this tool follows: always capitalize the first and last word, capitalize nouns, verbs, adjectives and adverbs, and keep articles (a, an, the), short conjunctions (and, but, or) and short prepositions (in, on, of, to) lowercase. Check the result for names and brands like “iPhone” or “eBay”, which no automatic tool gets right every time.
FAQ
How do I change all caps to normal text?
Paste the text and click Sentence case. Each sentence starts with a capital and everything else becomes lowercase. Then fix any names by hand.
Does the case converter work with other languages?
Yes. It handles accented and non-English letters such as é, ü, ñ and Cyrillic or Greek text. Scripts without capital letters, such as Hindi or Chinese, stay as they are.
What is the difference between Title Case and Capitalize Each Word?
Title Case keeps short words like “of”, “and” and “the” lowercase in the middle of a title. Capitalize Each Word capitalizes every single word.
Is my text stored anywhere?
No. The conversion happens in your browser and nothing is sent to our server.
