Case Converter
About this Tool
The Case Converter tool allows you to easily transform the case of your text. Whether you need your text in all uppercase, all lowercase, sentence case, or title case, this tool provides a quick and easy solution. It works by analyzing the input text and applying string manipulation techniques to change the casing of each character or word as per the selected option. This solves the common problem of manually editing text to fit specific formatting requirements, saving time and reducing errors in documents, emails, or code.
How does it work? The tool takes your input string and uses JavaScript string methods like toUpperCase(), toLowerCase(), or custom logic for title and sentence case. For title case, it capitalizes the first letter of each major word, ignoring minor words like "the" or "and" unless specified. Sentence case capitalizes only the first letter of each sentence. This automation eliminates the tedium of manual corrections, especially for large texts.
