How to convert text to uppercase, lowercase, or title case
A heading typed in all caps, a column of labels that should be identifiers, a caps-lock accident — retyping is never the answer. Paste the text, pick the target case, and copy the result.

Tips that save a second try
Identifier modes like camelCase and snake_case discard punctuation and spacing to build tokens — use title or sentence case for prose you want to keep readable.
Title case applies simple capitalization, not editorial small-word rules, and acronyms can change too — “API” becomes “Api”, so skim names afterward.
Sentence case is the fastest fix for caps-lock accidents: it lowercases everything, then capitalizes the start of each sentence.
Common questions
What is the difference between title case and sentence case?
Title case capitalizes every word, like a headline. Sentence case capitalizes only the first word of each sentence, like normal prose — pick whichever your style guide expects.
Does it work with accented or non-English text?
Yes. Word detection follows Unicode letters and numbers, so accented characters and non-Latin scripts are treated as part of words, not separators.
