CaseShift

About

CaseShift is a lightweight Chrome extension that helps you fix text formatting in seconds: change case, tidy capitalization, and get your text ready to paste anywhere.

Who it’s for

Perfect for writers, editors, managers, designers, developers, and anyone who constantly copies text between briefs, emails, spreadsheets, chats, and CMS tools. It’s especially useful when text arrives in ALL CAPS, all lowercase, or with chaotic Capital Letters all over the place.

What CaseShift does

Five quick conversion modes:

- AA — UPPERCASE  
- aa — lowercase  
- Aa Aa — Title Case  
- aA — invert case  
- Aa. Aa. — Sentence case  

It works with any language that distinguishes between uppercase and lowercase letters (English, German, French, Spanish, and many more).

How it works

1. Open the CaseShift popup from the Chrome toolbar.  
2. Paste or type your text.  
3. Choose the mode you need (AA, aa, Aa Aa, aA, Aa. Aa.).  
4. Copy the result and paste it wherever you need it.

The extension remembers your last selected mode using browser storage, so repeated tasks get even faster. No cluttered settings — just a compact interface and quick case conversion.
