Randomize the letter case of any text instantly. This tool lets you shuffle uppercase and lowercase characters or convert text into common developer and writing formats.
Everything runs directly in your browser. No data leaves your device.
How It Works
Paste or type your text into the input box. Then choose a conversion mode and click Convert.
Available modes include:
- UPPERCASE
- lowercase
- Title Case
- Sentence case
- aLtErNaTiNg
- RaNdOm (shuffle case unpredictably)
- camelCase
- snake_case
- kebab-case
- PascalCase
In Random mode, you can adjust the randomness level using the slider. Lower values keep the text closer to its original form. Higher values increase variation.
Example
- Input:
bEst ONLiNe gUiTar lessONS. - Random Output:
besT onLine GuiTAr LEssOns.
