About this tool
Text arrives in the wrong case more often than it should: a name typed in full capitals, a heading pasted from somewhere that shouted it, a paragraph where the caps lock was on for the first half. Four conversions cover almost all of it, and the result comes with a copy button and a plain text file if you need to move it somewhere else.
UPPERCASE and lowercase are safe — they push every letter one way and nothing is lost that was not going to be lost anyway. Title Case and Sentence case are more destructive than they look. Both flatten the text to lowercase before raising the letters they think should be capitals, so an acronym or a surname that was correctly capitalised comes back looking wrong. Check the output rather than pasting it straight into a form.
The casing is locale-aware, and scripts that have no notion of case pass through exactly as they went in. For a page written entirely in Hindi the tool will do nothing at all, which is the honest answer rather than a bug. Mixed text — an English product name inside a Hindi sentence — will have the English part converted and the rest left alone.
How to use this tool
- Paste your text. The box takes anything from a headline to several pages. An empty box gives you an error rather than an empty file.
- Choose what to convert to. UPPERCASE, lowercase, Title Case or Sentence case.
- Run it and take the result. The converted text appears on the page with a copy button, and there is a download as converted-text.txt if you would rather have a file.
What this tool does not do
- It does not protect acronyms, brand names or proper nouns when converting to Title or Sentence case.
- It does not follow any publisher's title-case rules about small words.
- It has no effect on Devanagari or any other script without letter case.
- It does not fix spacing, punctuation or spelling — only case.
Common questions
What will it do to Hindi text?
Nothing, and that is correct. Devanagari has no capital and small letters, so there is nothing to convert. The same is true of Tamil, Bengali, Gujarati and Arabic. If your text mixes English words into Hindi, only the English words change.
Why did NASA become Nasa?
Title Case and Sentence case both lowercase the whole text first and then raise the letters that should be capitals. Acronyms and proper nouns do not survive that. If you need them back, fix them afterwards, or use UPPERCASE and lowercase, which only change case in one direction.
What does Sentence case treat as a sentence?
A full stop, question mark or exclamation mark followed by a space starts a new one. That is right most of the time and wrong for abbreviations: “dr. gupta” comes out as “Dr. Gupta”, which happens to look fine, while “i live on m.g. road” gets a capital after each dot.
Does Title Case follow a style guide?
No. Every word gets a capital letter, including “of”, “the” and “and”. Publishers have rules about which small words stay lowercase; this does not implement any of them.
Is my text sent anywhere?
No. The conversion runs in the page, the copy goes to your clipboard, and the download is built on your device. Nothing is uploaded.
