How it works: Transforms blocks of text into standard grammatical or programming case formats while displaying live character counts, word counts, and modified letter tallies. Supports 11 comprehensive modes: Sentence case, lower case, UPPER CASE, Title Case (following Chicago Manual of Style editorial capitalization where minor words like 'of', 'and', 'the' stay lowercase unless starting a sentence), Capitalized Case, alternating meme case, inverse case, camelCase, PascalCase, snake_case, and kebab-case. Developer identifier formats automatically detect and split boundaries across camelCase, PascalCase, and acronyms (converting 'myVariableName', 'parseHTMLString', and 'userID' into clean separated words).
Why it matters: Accidental CAPS LOCK prose, disorganized copy-pasted headlines, and raw text strings frequently need immediate normalization before pasting into customer emails, formal publications, or codebase repositories. In software engineering, inconsistent casing across database columns (snake_case), API models (camelCase), and class declarations (PascalCase) causes silent deserialization bugs and schema mismatches. The built-in acronym and brand preservation engine keeps initialisms like NASA, API, and FBI, as well as modern camel-cased brands like iPhone, eBay, and McDonald's, perfectly capitalized even when normalizing surrounding text. The visual X-Ray inspection pane highlights every modified character with high-contrast pills so you can audit the transformation before copying.
