The Complete Guide to Text Case Conversion
Whether you are writing code, formatting a headline, or cleaning up text pasted from a PDF, switching between text cases manually is slow and error-prone. Our Text Case Converter handles eight common formats instantly, entirely in your browser.
Why Case Matters in Programming
Programming languages and style guides expect specific naming conventions — variables in camelCase, classes in PascalCase, and file names or CSS classes in kebab-case or snake_case. Using the right case avoids linting errors and keeps code consistent.
Supported Case Formats
- UPPERCASE / lowercase: Converts every letter for headings, acronyms, or normalized search text.
- Title Case: Capitalizes the first letter of every word — ideal for headings and titles.
- Sentence case: Capitalizes only the first letter of each sentence, like standard prose.
- camelCase / PascalCase: Used for JavaScript variables, functions, and class names.
- snake_case / kebab-case: Common in Python variables, file names, URLs, and CSS classes.
- aLtErNaTiNg CaSe: A fun, mocking text style popular on social media.
Common Use Cases
- Renaming variables when switching between JavaScript (camelCase) and Python (snake_case).
- Formatting blog titles and headings into consistent Title Case.
- Generating clean, URL-safe kebab-case slugs from a page title.
- Fixing text pasted with the CAPS LOCK key accidentally left on.
