How to use the alternating case converter

- Select Start with uppercase to make the first letter uppercase.
- Select Ignore spaces when alternating if spaces must not change the pattern.
- Read the result in the output field.
- Select Copy to copy the result.
Clear Start with uppercase if the first letter must be lowercase. The output then starts with a pattern such as aLtErNaTe.
How alternating capital and lowercase letters work
The converter reads the input from left to right. It changes the first letter to the selected case. It changes the next letter to the other case. It continues this pattern to the end of the input.
The output uses standard letters. It does not use decorative Unicode characters. You can paste the output into most fields that accept text.
The converter can also change letters in other alphabets when the letters have uppercase and lowercase forms. It keeps symbols that do not have case forms.
When to use alternate capital letters
Use alternate capital letters for informal text. Common uses include short jokes, meme captions, display names, and chat messages.
Alternating case often shows sarcasm or mockery. Review the meaning before you send the text. Do not use this style when the reader can mistake your intent.
Long alternating text can be difficult to read. Use a short phrase when possible. Use normal sentence case for instructions, formal messages, and important information.
Pattern settings
Start with uppercase
Select this option to start the pattern with an uppercase letter.
Input: hello
Output: HeLlO
Clear the option to start the pattern with a lowercase letter.
Input: hello
Output: hElLo
Ignore spaces when alternating
Select this option to apply the pattern to letters only. Spaces, numbers, and punctuation stay in the output, but they do not change the case of the next letter.
Clear the option to let each non-letter character change the next letter case. This setting can make the first letter of each word different.
Examples
| Input | Start case | Ignore spaces | Output |
|---|---|---|---|
hello world | Uppercase | No | HeLlO WoRlD |
hello world | Lowercase | No | hElLo wOrLd |
hello world | Uppercase | Yes | HeLlO wOrLd |
hello world | Lowercase | Yes | hElLo WoRlD |
Numbers and punctuation do not change form. The setting controls whether these characters change the next letter case.
