How does upside-down text work?

Upside-down text uses Unicode characters that look like flipped versions of regular letters. These are actual Unicode code points, so the result can be pasted anywhere that supports Unicode.

What does 'Remove duplicates' do?

It removes any line that appears more than once, keeping the first occurrence. Useful for deduplicating lists of emails, usernames, or any other line-based data.

Can I sort lines alphabetically?

Yes. Use Sort A-Z or Sort Z-A. Sorting is case-insensitive by default and handles numbers correctly (1, 2, 10 instead of 1, 10, 2).

Does shuffle use true randomness?

Shuffle uses the Fisher-Yates algorithm with Math.random(). It is not cryptographically secure but is sufficient for non-security purposes.
