Case Converter

Key features

• Eleven conversions in one grid: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, aLtErNaTiNg and Reverse.
• Programmer styles split your text on any non-alphanumeric run, so 'user profile-page' cleanly becomes userProfilePage or user_profile_page.
• Input and output sit side by side with live character counts, and your original text is never modified.
• The active conversion stays highlighted so you can compare styles by clicking through them.
• Copy button moves the converted result straight to your clipboard.

How it works

1. 1

   Paste your text

   Drop the source text into the Input panel on the left — its character count shows underneath.

2. 2

   Pick a conversion

   Click any style button in the Conversions grid. The result appears in the Output panel and the button lights up.

3. 3

   Compare styles freely

   Click different buttons to preview other cases; each one re-converts from your untouched original input.

4. 4

   Copy the result

   When the output looks right, hit Copy to grab it, or edit the input and click the style again to redo.

Tips for better results

• 💡For variable and column names, camelCase and snake_case ignore punctuation entirely — they rebuild from letter and digit runs only.
• 💡Title Case capitalizes the first letter of every word; Sentence case only capitalizes after ., ! or ? — pick per your style guide.
• 💡Reverse is a quick way to spot homoglyph issues or just flip text for fun.
• 💡Conversions work on any length, but very long documents are easier to handle in section-sized chunks.
