What is Snake Case?
Snake Case is a naming convention where words are separated by underscores (_) and all letters are typically lowercase. The name comes from the resemblance to a snake’s movement, with underscores creating the segmented appearance.
Snake Case is widely used in programming languages, especially:
- Python – Variable names, function names, and module names
- Ruby – Variable names, method names, and file names
- C – Variable names, function names, and macro names
- PostgreSQL – Table names, column names, and database objects

Frequently Asked Questions
What is Snake Case and why is it used?
Snake Case is a naming convention where compound words are written in lowercase and separated by underscores (e.g., “first_name”). It’s called “snake case” because the underscores create a segmented appearance like a snake. It’s widely used in programming because it’s highly readable and follows many language conventions.
When should I use Snake Case?
Use Snake Case for variable names, function names, and file names in languages like Python, Ruby, and C. It’s also the standard convention for database table and column names in SQL databases, making it essential for backend development.
How does this differ from Camel Case?
Snake Case uses underscores to separate words and keeps all letters lowercase (e.g., “user_name”), while Camel Case capitalizes the first letter of each word except the first and removes spaces (e.g., “userName”). Snake Case is preferred in Python, while Camel Case is common in JavaScript.
Does the tool handle special characters and numbers?
Yes, the tool properly handles special characters, numbers, and unicode characters. It intelligently removes or converts special characters while preserving the meaning of your variable names and converting them to proper Snake Case format.
Can I convert multiple variable names at once?
Yes! You can paste multiple lines of text, and the tool will convert each line to Snake Case format. This is perfect for batch converting variable names or processing lists of identifiers for your Python projects.
Is my code data secure?
Absolutely! All text processing happens directly in your browser. Your variable names and code snippets are never sent to our servers, ensuring complete privacy and security.
