Convert Case & Slug from Text API

What it does

String Case Converter turns one input string into a set of common text cases and a URL slug. Send the text field in the request body, and get back the converted forms plus the original input and word_count.

Use it when you need to normalise user-entered text for URLs, code identifiers, headings, or labels. The response includes slug, dot.case, camelCase, PascalCase, Title Case, kebab-case, snake_case, CONSTANT_CASE, and Sentence case, so you can pick the format that fits your system without reimplementing string transforms in your app.

This is useful in content pipelines, admin tools, CMS workflows, and developer utilities where the same text needs to be reused across multiple naming conventions. If you are generating slugs from titles or converting strings for frontend and backend conventions, this keeps the conversion logic in one place.

String Case Converter is a small, focused developer tool: one text input, multiple case outputs, and a predictable response shape.
