Case Converter

The NOFYI Case Converter fixes capitalisation in seconds — turn shouted ALL-CAPS text into clean Sentence case, or a lowercase draft into proper Title Case, without retyping it.

What is Case Converter?

A Case Converter converts text between UPPER CASE, lower case, Title Case, and Sentence case. It changes how letters are capitalised while keeping your words, punctuation, and line breaks the same.

How to Use the Case Converter

1. Paste or type your text into the box.
2. Choose the case you want: UPPER, lower, Title Case, or Sentence case.
3. Click Convert to transform the text.
4. Click Copy to copy the result, then paste it where you need it.

Case Example

With Title Case, “hello world” becomes “Hello World” — the first letter of each main word is capitalised.

What You Can Use It For

• Headings and titles — make them consistent across a document or site.
• Fixing pasted text — repair text copied in ALL CAPS from PDFs or forms.
• Social posts and emails — clean up capitalisation before publishing or sending.
• Data cleanup — standardise names and labels in lists and spreadsheets.

Limitations to Know

• Title Case rules for small words (a, an, the, and, of, to) vary by style guide, so check the result against your house style.
• Check names, acronyms, and brand names manually — converters cannot know that “NASA” should stay uppercase or “McDonald” keeps its internal capital.
• Sentence case depends on punctuation. Missing full stops can cause wrong capitalisation after abbreviations.

Frequently Asked Questions

Does it change my words or spelling?

No. It only changes capitalisation. Words, spelling, and punctuation stay the same.

What is the difference between Title Case and Sentence case?

Title Case capitalises the first letter of most words. Sentence case capitalises only the first letter of each sentence, plus proper nouns.

Will it preserve my line breaks?

Yes. Line breaks and paragraph structure are kept in the converted output.

Can I convert a whole document?

Yes, for normal-length text. For very long documents, convert in sections so you can check names and acronyms as you go.
