Case Converter

About Case converter

The case converter rewrites your text in one of nine styles with a single click: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case and aLtErNaTiNg. Writers use it to fix a headline typed with caps lock on, and developers use it to turn a plain phrase into a variable name or URL slug.

How to use it

1. Paste your text into the Text to Convert box.
2. Click the button for the style you want. There is no separate convert button.
3. Read the output under Converted Text.
4. Click Copy, or press a different style button to convert the same input again.

When to use it

• Repairing a paragraph or heading that was typed in the wrong case.
• Turning a feature description into a camelCase variable or a snake_case database column.
• Making a URL slug from a title with the kebab-case button.
• Producing sentence-case text from a pasted block that was entirely in capitals.

Questions about Case converter

Does Title Case follow style-guide rules?

No, it is simple. Everything is lowercased first and then the first letter of every space-separated word is capitalized, so small words such as of and the are capitalized too.

Why did accented letters disappear in snake_case or kebab-case?

Those two modes keep only English letters, digits and the joining character. Anything else, including accents and punctuation, is removed, so Crème brûlée becomes crme_brle. Transliterate first if you need to keep those letters.

How does Sentence case decide where sentences start?

It lowercases the text, then capitalizes the first letter and any letter following a full stop, question mark or exclamation mark. Names and the pronoun I are lowercased, so fix those by hand.

What defines a word boundary in camelCase and PascalCase?

Any run of characters that is not a letter or digit acts as a boundary. Spaces, hyphens, underscores and punctuation all mark the start of a new capitalized word and are then dropped.
