How to fix text typed with caps lock on

You type a paragraph without looking up, and it comes out as “hELLO, i WANTED TO ASK ABOUT”. Or a colleague sends a document entirely in capitals, which reads like shouting. Retyping is not necessary: case conversion fixes it in seconds.

Fix it step by step

1. Paste the text into the Case Converter.
2. Choose Sentence case. Each sentence starts with a capital and the rest becomes lower case.
3. Read through, put capitals back on names and acronyms, and copy the result.

For accidental caps lock specifically, where every letter's case is the opposite of what you meant, the iNVERSE cASE option flips each letter back exactly, including the capitals you intended.

Which case to choose

• Sentence case for paragraphs, emails and messages.
• Title Case for headings, document titles and book names. See title case rules for which small words stay lower case.
• lowercase for email addresses, web addresses and tags.
• Inverse case for text typed with caps lock on, so that intended capitals return.

What to check by hand

A converter cannot know which words are names. After converting, look for:

• People, places and organisations: “london” should be “London”.
• Acronyms: “nasa”, “pdf” and “uk” need their capitals back.
• The word “I” in English.
• Brand names with unusual capitals, such as iPhone or YouTube.
• Days and months, which are capitalised in English but not in many other languages.

For a long document, use your editor's find and replace to fix repeated names in one go.

Shortcuts in common programs

• Microsoft Word: select the text and press Shift+F3 to cycle through lower case, UPPER CASE and capitalised words.
• Google Docs: Format → Text → Capitalisation offers lower case, UPPER CASE and Title Case.
• Phones: no built-in option in most keyboards; paste into a converter.

Stop it happening

• Windows: Settings → Accessibility → Keyboard has a Toggle Keys option that plays a sound when Caps Lock is switched on.
• macOS: System Settings → Keyboard → Keyboard Shortcuts → Modifier Keys lets you change what Caps Lock does, or turn it off entirely.
• Phones: double-tapping Shift turns on caps lock on most keyboards; a single tap only capitalises the next letter.

Data in all capitals

Exports from older systems often store names and addresses in capitals, such as “JOHN SMITH, 12 HIGH STREET”. “Capitalise Every Word” gives “John Smith, 12 High Street”, which is right for most entries. Names such as McDonald, O'Brien and van der Berg, and postcodes, need a manual check, because simple rules cannot get them all right.

Clean up at the same time

Text pasted from emails or PDFs often has extra spaces and broken lines too. Run it through the Text Cleaner first, then convert the case. For code-style cases such as camelCase and snake_case, see camelCase vs snake_case vs kebab-case.
