snake_case Converter

How does this tool convert text to snake_case?

It splits your text into words at spaces, punctuation, and symbols, lowercases each word, and joins them together with underscores.

What happens to existing uppercase letters or camelCase input?

All letters are lowercased regardless of their original casing, so camelCase or PascalCase input converts into properly lowercased, underscore-separated snake_case.

Are numbers and apostrophes preserved?

Numbers are kept as part of the word they appear in, and apostrophes inside words like don't are preserved as part of that word during conversion.
