Overview

Text case is more important than it might seem. The wrong capitalisation can make content look unprofessional, break naming conventions in code, cause sorting issues in databases, and even affect search engine processing of certain terms. Our Text Case Converter handles 10+ common case transformations: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, and alternating case. Each transformation is performed instantly as you paste or type text. This tool is invaluable for developers converting variable names between languages (JavaScript camelCase to Python snake_case), writers correcting accidental CAPS LOCK text, SEO professionals normalising keyword variations, data engineers cleaning text fields before import, and anyone who needs consistent capitalisation across large blocks of text. Process entire paragraphs, code snippets, lists of keywords, or headers in a single operation.

Frequently Asked Questions

What is Title Case?

Title Case capitalises the first letter of each major word. Minor words like "a", "an", "the", "of", "and" are typically kept lowercase unless they start the title.

What is camelCase?

camelCase joins multiple words together with no spaces, capitalising the first letter of each word except the first: e.g., myVariableName. Common in JavaScript and Java.

What is snake_case?

snake_case uses underscores between words, all lowercase: my_variable_name. Common in Python, Ruby, and database column names.

What is kebab-case?

kebab-case uses hyphens between words, all lowercase: my-variable-name. Commonly used in CSS class names, HTML attributes, and URL slugs.

Can this convert a full article to Title Case?

Yes. Paste your full article, blog post, or list and click Title Case. The tool applies proper capitalisation to the entire text at once.
