About Case Converter
Case Converter reshapes text into UPPERCASE, lowercase, Title Case, Sentence case, and programmer-friendly camelCase, snake_case, and kebab-case. Developers normalize variable names from pasted specs; marketers fix ALL CAPS headlines from PDFs; legal assistants adjust exhibit titles to match court style guides. Bulk conversion beats manually retyping hundreds of lines.
Title case rules vary by stylebook—this tool follows a consistent algorithm that may not match Chicago or AP on every edge case (short words, hyphenated terms). Always proofread proper nouns after conversion because automatic title casing can lowercase “iPhone” or “McDonald’s” incorrectly. Programming modes assume Latin identifiers; unicode identifiers may need manual review.
Paste from plain text sources when possible; hidden rich-text spans can insert odd spaces. Chain with Word Counter when converted copy must meet length limits, or with JSON Formatter when you embed strings in config snippets.
Do not paste secrets such as API keys just to change their case—logs and browser extensions can leak clipboard history. For public content, case conversion is low risk. For legal filings, human proofread remains mandatory after any automated text transform.
