Check Names and Code Identifiers

A case conversion does not know which words are names or acronyms. Read headings and sentences after converting them, especially when the text contains abbreviations or mixed capitalization.

When converting database names to code identifiers, check word boundaries and the destination language's rules. Changing text here does not rename references throughout a codebase or establish that an identifier is valid.

Working with Pasted Text

Use the tool to tidy capitalization in a draft or compare naming styles. Keep an original copy before applying another style if you need to preserve the starting capitalization.

Large inputs can be limited by browser resources. Follow your organization's handling requirements before entering confidential text into a web tool.
