Text Case Converter

What this generator does

Splits your text into words — handling runs of capitals, digits and separators — and writes those words out in eight conventions at once.

How to use this tool

1. Paste the text — a variable name, a heading, a phrase.
2. Convert it, and take whichever shape you need.
3. Check the split shown at the top if the result looks unexpected.
4. Every shape is produced at once, so there is nothing to choose first.

Understanding the controls

Your text

Up to two thousand characters. Underscores, hyphens, dots, slashes and spaces are all treated as word breaks, as are the case changes inside a name.

Common use cases

• Renaming a variable to match a codebase's convention
• Turning a heading into a file name or a URL slug
• Converting a column name between database and code styles
• Making a constant name from a phrase
• Checking how a converter splits an awkward name before relying on it

How this generator works

Each version is split back into words and compared against the original split — all eight must give the same words in the same order. The letters and digits are also compared between two of the versions to confirm none was lost or added. A wrong split is the one mistake a case converter can make, and it always produces output that looks correct.

Randomness and fairness

Nothing is random. The same text always converts the same way.

Limitations and good to know

• English word breaks: a run of capitals followed by a lower-case word is treated as two words, which is right for XMLHttp and wrong for a name that genuinely is all capitals.
• Punctuation other than separators is dropped, since none of these conventions can carry it.
• Accented letters are kept but not transliterated.
• Digits become words of their own, so version2 splits into three words rather than two.
