Why ALL CAPS is hard to fix

Capital text has thrown away information. "NASA STUDY SHOWS ICE LOSS IN GREENLAND" gives no clue about which words had capitals originally, so any tool has to make a sensible guess. This tool uses three things for that guess: a list of common short forms, a list of names and places, and a list of brand names that have capitals inside them, such as iPhone and eBay.

The check you still have to do yourself

No built-in list can know the names in your particular document. After converting, look for people, companies, products and place names. Also check words that can be both ordinary and a name — apple and Apple, march and March, polish and Polish. That last group is the only place where an automatic tool will confidently give you the wrong answer.

Frequently asked questions

Will short forms like NASA stay in capitals?

If your text has a mix of capital and small letters, yes — anything already in capitals is kept. If the whole text is in capitals, there is nothing left to keep, so the tool uses a built-in list of common short forms, brand names and place names instead.

What is the difference between sentence case and proper case?

Sentence case puts a capital on the first word of each sentence and on names: "The report from NASA arrived". Proper case puts a capital on every word: "The Report From Nasa Arrived". Use sentence case for normal writing and proper case for names and addresses.

Can I fix a whole document at once?

Yes. There is no limit, and each line is handled separately, so your paragraphs and lists stay exactly as they were.

How do I avoid this problem next time?

If the capitals are only for looks, do not type them. Type normally and use CSS text-transform: uppercase in your design. It looks the same on screen, but the real text stays readable, searchable and easy to change later.
