Frequently Asked Questions

What is snake_case used for?
snake_case is common in Python variables, database column names, file names, and API fields where words are joined with underscores.
What is the difference between snake_case and kebab-case?
snake_case joins words with underscores (my_file) while kebab-case joins them with hyphens (my-file).
Can I convert camelCase to snake_case?
Yes. The converter detects camelCase boundaries, so totalAmount becomes total_amount.
