How It Works & Technical Architecture

The Case Converter tokenizes your input text into individual words, identifiers, and punctuation delimiters.

For programming cases (camelCase, snake_case, kebab-case), it strips whitespace and non-alphanumeric characters, capitalizing or delimiting tokens according to target language rules.

For Title Case, a grammatical dictionary checks word roles to ensure articles, conjunctions, and prepositions are appropriately lowercased.

Frequently Asked Questions

What is Title Case and how does Softnag handle small words?

Title Case capitalizes the first letter of major words while keeping short articles, conjunctions, and prepositions (like "in", "the", "and", "of") lowercase, adhering to AP and Chicago editorial standards.

What is the difference between camelCase and PascalCase?

In camelCase, the first word is lowercase while subsequent words start with a capital (e.g., myVariableName). In PascalCase, every word starts with a capital letter (e.g., MyVariableName).

What is snake_case and kebab-case?

snake_case separates words with underscores (e.g., user_profile_data), commonly used in Python and SQL. kebab-case separates words with hyphens (e.g., user-profile-data), widely used in URLs and CSS.
