Snake_Case Converter

Snake_Case Converter turns space-separated text or camelCase identifiers into lowercase_with_underscores format — the standard for Python variables, database column names, and many REST API field names.

Consistent naming conventions reduce bugs and make code easier to read. Converting a batch of names in one go is far faster than editing each identifier by hand.

Tip: After converting, scan for consecutive underscores that may have come from punctuation in the source text — those can cause unexpected behaviour in some frameworks.
