How it works
Reverse caps swaps the case of every letter: capitals go small and small letters become capitals. That repairs a line typed with Caps Lock on, where hELLO should have been Hello. Other names are inverse case and toggle case.

Why Caps Lock text comes out reversed
With Caps Lock on, letters arrive as capitals, and on keyboards where Shift undoes Caps Lock a shifted letter arrives small. A sentence typed the usual way then has every capital exactly backwards, so one swap puts all of it right.
What stays as it is
Digits, punctuation and letters of scripts that have no capitals, such as Chinese or Arabic: 東京 Tokyo becomes 東京 tOKYO.
Two letters that do not come back
The German ß becomes SS and returns as ss: straße, STRASSE, strasse. A Greek final sigma, ς, becomes Σ and returns as the plain σ.
- All capitals with no small letters? A swap only gives all small letters, so copy the Sentence case row.
- For capitals that alternate lIkE tHiS, the mocking text generator is the page.
Questions and answers
What is toggle case?
Toggle case is a word processor’s name for reverse caps: the case of every selected character is switched, so Hello becomes hELLO. Case inverter and reverse case are names for the same change.
How do I reverse caps lock text?
Paste the line. Every letter switches at once, accented ones included: tHE MEETING IS ON mONDAY becomes The meeting is on Monday, and cAFÉ éCLAIR becomes Café Éclair. Nothing is retyped.
Is reverse case the same as reverse text?
No. Reverse case changes capitals and small letters and leaves every letter in its place. Reverse text writes the letters in the opposite order, last one first, which this page does not do.
