String Utils

This tool offers 10 actions: Reverse Text (flip all characters), Reverse Lines (flip line order), Sort A-Z, Sort Z-A, Remove Duplicates (keep unique lines), Remove Empty Lines, Shuffle Lines (random order), Trim Whitespace (from each line), Remove Line Breaks (join into one line), and Add Line Numbers.

Sort A-Z and Sort Z-A use locale-aware string comparison, which handles accented characters correctly. The sort is line-based: each line of your text is treated as one item and reordered alphabetically or in reverse alphabetical order.

Remove Duplicates keeps only the first occurrence of each line and removes all subsequent identical lines. The comparison is exact (case-sensitive), so "Hello" and "hello" are treated as different lines. The original order of remaining lines is preserved.

Yes. Each action transforms the text in-place, so you can apply multiple actions in sequence. For example, you could first Remove Empty Lines, then Sort A-Z, then Remove Duplicates to clean up a list.

The tool works with whatever text you paste into it. Modern browsers handle UTF-8 natively, so characters from any language, including emojis and special symbols, are supported. All processing happens locally in your browser.
