What is camelCase?
camelCase is a naming convention where the first word is written in lowercase, and each subsequent word starts with a capital letter, with no spaces between words (e.g., myVariableName). It is the standard convention for variables and functions in JavaScript, TypeScript, and Java.
When to use this converter
Use this tool when migrating database schemas (which often use snake_case) to JSON APIs, or when converting readable column headers into programming variables. Doing this manually is error-prone, but our local browser script handles it instantly.
