What is the difference between case-sensitive and case-insensitive alphabetical sort?

Case-sensitive sort orders uppercase letters before lowercase letters (A, B, C, a, b, c). Case-insensitive sort treats "Apple" and "apple" as equivalent and orders them by their letter sequence regardless of capitalization, which is the more natural sort for most lists.

How does numeric sort work for lines that are not plain numbers?

Numeric sort parses the leading number in each line using JavaScript's parseFloat. Lines that do not start with a number (NaN) are grouped at the end of the sorted output. This lets you sort lines like "12 apples" and "3 oranges" by their numeric prefix.

Does Random shuffle produce a truly random order?

The tool uses a Fisher-Yates (Knuth) shuffle, which produces a statistically unbiased random permutation. Because it runs in the browser using Math.random(), it is suitable for casual randomization but not for cryptographic purposes.

What does Remove Duplicates do when lines differ only in case?

Remove Duplicates performs a case-sensitive comparison by default — "Apple" and "apple" are treated as different lines. Apply the Trim Whitespace option before deduplication if you want to also collapse lines that differ only in leading or trailing spaces.

Is my text sent to a server?

No. All processing happens entirely in your browser. Your text never leaves your device, making this tool safe to use with sensitive or confidential content.

How do I sort a list of numbers that include decimals or negatives?

Use the Numeric comparison mode. The parser recognizes negative signs and decimal points, so lines like "-3.5", "0", and "2.1" will sort correctly in ascending or descending order.
