Text ends up in the wrong case more often than you'd expect. Someone typed with caps lock on by accident, a heading got pasted from a source that used a different style, or you just need something in all caps for a design mockup. This tool fixes that in one click, converting a block of text to uppercase, lowercase, title case, or sentence case without you retyping anything.
How to use it
- Paste the text you want to change into the box.
- Click uppercase, lowercase, title case, or sentence case.
- Look over the result underneath.
- Copy it once it's right.
- Try a different option if the first one wasn't what you had in mind.
When it helps
- Fixing text that got typed in all caps because caps lock was on.
- Making headings consistent across a document in title case.
- Cleaning up text copied from a PDF where the capitalisation is a mess.
- Getting text into lowercase for a system that expects lowercase usernames.
- Quickly generating an all caps version of a label for a design mockup.
Good to know
- Title case here capitalizes every word, which is fine for a heading but strict style guides usually want small words like 'and' left lowercase. You may need to fix those by hand.
- Sentence case only capitalizes the letter after a period, question mark, or exclamation point, so check paragraph breaks in oddly formatted text.
- If you're not sure what case your text is already in, run it through lowercase first, then apply whatever case you actually want.
- When formatting headings for a website, check your style guide first. Some prefer title case for every heading, others use sentence case for a more casual tone.
- If you're preparing text for a spreadsheet column that expects a consistent case, run the whole column through at once rather than fixing entries one by one.
Questions
Will this handle acronyms like NASA correctly?
Not reliably. The tool can't tell an acronym from a normal word, so converting to title case or sentence case will probably lowercase it. Worth a quick scan afterward to fix any acronyms by hand.
Can I convert just part of my text?
Yes. Paste only the part you want changed, convert it, then paste it back into the rest of your document.
Does this work for languages other than English?
Basic case conversion works for most languages that use the Latin alphabet. Languages with different capitalisation rules, or non-Latin scripts, might not convert the way you expect.
Does converting to lowercase affect proper nouns?
Yes, lowercase applies to every letter including names and places, so you'll likely need to recapitalize proper nouns by hand afterward.
Can I convert code variable names with this?
It works on any text including code, but programming conventions like camelCase aren't among the preset options here, so you may need to adjust manually for those.
Does this change the case of text inside quotation marks?
Yes, it treats everything you paste as one block of text, quotation marks included, so anything inside quotes converts the same way as the rest.
