About Case Converter
ToolsOfIndia built the Case Converter for writers, coders and social media managers who want straight answers in plain language. Convert text between every common case - UPPER, lower, Title Case, Sentence case, camelCase, snake_case, kebab-case and the playful aLtErNaTiNg case - in one click, with the result ready to copy. Developers use it to normalise identifiers and constant names, writers use it to fix capitalisation in a draft, and marketers use it for social media formatting, all without retyping. The tool preserves the original spacing and punctuation, and the camelCase and snake_case modes strip surrounding symbols so the result pastes cleanly into code. Because everything is local, the text never leaves the browser, which suits code with sensitive variable names. It is the small utility that saves endless re-keying when a case is wrong. Privacy is the whole point of keeping it client-side: no uploads, no accounts, no copy of your writing sitting anywhere but your own machine. In practice people reach for it most when converting a title to Title Case, when making a snake_case variable from a phrase, or while fixing accidental caps lock text. It works just as well on a budget Android phone as on an office desktop, over any connection.

What is toggle case?
Toggle case reverses the case of each letter - uppercase becomes lowercase and vice versa. Also known as swap case or reverse case.
