Convert text between UPPERCASE, lowercase, Title Case, Sentence case, camelCase, and snake_case instantly, free.
Powered by AIVEXA
The Text Case Converter instantly switches any pasted text between UPPERCASE, lowercase, Title Case, Sentence case, camelCase and snake_case — formats developers, writers and students each need for different purposes, from variable naming conventions in code to formatting headlines or fixing accidentally-capslocked messages.
camelCase and snake_case in particular are naming conventions used in programming: camelCase (firstName) is common in JavaScript and Java, while snake_case (first_name) is the convention in Python and SQL — this tool converts freely between all six formats without needing to retype anything.
Title Case capitalizes the first letter of every major word (This Is A Title), while Sentence case only capitalizes the first letter of the sentence (This is a sentence) — Title Case is typical for headings, Sentence case for body text.
Yes, paste any length of text — a sentence, paragraph or full document — and the conversion applies to the entire block instantly.
