About this tool
Transform text into uppercase, lowercase, title case, sentence case, camelCase, or snake_case without retyping it. Uppercase and lowercase change every cased letter. Title case capitalizes words for heading-style text, sentence case normalizes prose-style capitalization, camelCase joins words with internal capitals, and snake_case joins lowercase words with underscores. “monthly sales report” becomes “MONTHLY SALES REPORT,” “Monthly Sales Report,” “monthlySalesReport,” or “monthly_sales_report,” depending on the selected format. Convert an all-caps email into calmer lowercase, prepare a heading for a slide, or turn a phrase into a programming identifier. It is also useful when copied spreadsheet labels arrive with inconsistent casing. Type or paste into Input, select a case type, and copy the Output. Automated title and sentence casing cannot infer every proper noun, acronym, brand spelling, or style-guide exception. For example, “NASA visits New York” may need manual corrections after normalization. Camel and snake modes are formatting aids, not full identifier validators; punctuation and non-Latin text may behave according to JavaScript’s built-in character rules. Review the result before publishing or placing it in source code.
