Text Case Converter

Convert text cases for writing and code

ToolsOfWeb’s Text Case Converter helps you quickly switch between common text styles like UPPERCASE, lowercase, Title Case, Sentence case, and developer-friendly formats such as camelCase, PascalCase, snake_case, and kebab-case. Paste text, pick a conversion, and copy the result instantly. The conversion runs fully client-side in your browser, so your text isn’t sent to a server for processing. It’s ideal for fixing headings, normalizing pasted content, or converting identifiers when writing code, API keys, or file names. Choose a case style, preview the output, and copy it with one click. Developer cases also normalize separators and whitespace, which is helpful when converting from sentences to code-friendly naming conventions.

For writing, Title Case can make headings look clean and consistent, while Sentence case is helpful for paragraphs that were pasted in all caps. For developers, case conversion is a daily task when switching between naming conventions—variables (camelCase), types (PascalCase), environment keys (UPPERCASE), and file slugs (kebab-case). This tool removes manual editing so you can focus on the content rather than formatting.

Popular conversions

• Title Case for headings and titles
• camelCase / snake_case for code identifiers
• kebab-case for URL slugs

When creating URL slugs, kebab-case is usually preferred because it’s readable and widely used. For variables and functions, camelCase is common in JavaScript, while snake_case is common in Python and data pipelines. If you’re copying text from PDFs or emails, converting to Sentence case can quickly clean up accidental ALL CAPS paragraphs. Conversions happen instantly in the browser and you can copy the output with one click.

If you’re preparing content for publishing, consistent casing makes pages look more professional. Use Title Case for article titles, Sentence case for paragraphs, and keep acronyms consistent. For developers, converting a phrase into camelCase or snake_case is a quick way to create variable names without manual editing.
