Frequently Asked Questions
Is snake case the same as underscore notation?
Yes, snake case is often referred to as underscore notation since it uses underscores to separate words.
Should I use snake case or camel case?
This depends on your programming language. Python typically uses snake case, while JavaScript conventionally uses camel case. Follow the conventions of the language you're working with.
Can snake case include numbers?
Yes, numbers can be included in snake case identifiers (e.g., user_id_123). However, identifiers shouldn't start with numbers in most programming languages.
How do I convert camel case to snake case?
Simply paste your camel case text into our converter and click the convert button. Our tool will automatically insert underscores before capital letters and convert everything to lowercase.
Is snake case case-sensitive?
By definition, snake case is all lowercase. However, some variations like "Upper Snake Case" (e.g., USER_ACCOUNT_NAME) exist for constants.
