Convert text to aLtErNaTiNg CaSe.

This tool converts text into aLtErNaTiNg CaSe -- alternating uppercase and lowercase letters, the style popularized as "mocking spongebob text". Only alphabetic characters toggle case; numbers, spaces, and punctuation pass through unchanged and don't consume a toggle step.
Type or paste your text. The alternating-case version appears instantly, ready to copy.
The generator starts with an uppercase letter and then alternates strictly between uppercase and lowercase, one letter at a time, for the entire text. The alternation counts letters only. Spaces, digits, punctuation, emoji, and line breaks are copied through unchanged and do not use up a turn. The pattern also does not restart at a new word or a new line: it simply continues with whichever case is next. This matters because the result depends on how many letters came before a given position, not on where the word begins.
Only the basic English letters a to z (upper or lower) take part in the alternation. Other characters, including accented letters and letters from other alphabets, pass through unchanged and do not affect the pattern.
Because the tool overrides the original capitalization of every letter, you do not need to lowercase your text first. The same input always produces the same output.
The style is mostly decorative or humorous. People use it for the mocking tone in memes and social posts, playful usernames, stylized captions, and comments where they want to imply sarcasm. Designers sometimes use it for a quirky logo effect or for testing how a font handles alternating capitals. It can also serve as a quick way to check that a system treats capitalization consistently, since the output contains a known mix of cases.
To change which case comes first, add or remove a leading letter. For example, adding a temporary single letter at the start flips the whole pattern, and you can delete that letter from the result afterward. If you paste long text, remember that the pattern continues across all lines, so a paragraph that begins after an odd number of letters will start with a lowercase letter. Copy the finished result with the copy button or download it as a text file, then paste it wherever you need it. Always preview it where you will publish it, because some platforms restyle or strip unusual capitalization.
No -- only letters toggle the upper/lower case, so a number or space in the middle of a word doesn't disrupt the alternating sequence that continues on the next letter.
No -- the conversion happens entirely in your browser.
No. It continues across the whole text, counting letters only. A word can begin with a lowercase letter if the previous word ended on an uppercase letter.
The tool always starts with uppercase. A workaround is to add one temporary letter at the front so the pattern flips, then delete that letter from the output.
They pass through unchanged and do not count toward the alternation, which applies only to the basic letters a to z.
It works technically, but the result is hard to read and less accessible. It is best for short phrases and playful posts.
