## Features

### Bidirectional

Convert lines to a separated string _or_ split a separated string back to lines — one tool for both directions with a single mode toggle.

### Any Separator

Presets: comma, pipe, tab, space, semicolon, slash. Or type any custom separator — multi-character separators work too.

### Quote Wrapping

Wrap each item in single quotes, double quotes, or backticks — ideal for SQL IN clauses, JavaScript arrays, or shell commands.

### Clean Options

Trim whitespace, remove empty items, deduplicate, and sort A–Z — all independently toggleable so you get exactly the list you need.

### Item Preview

Every output item appears as a numbered chip so you can review the list visually before copying — perfect for spotting duplicates or empty items.

### All Languages + RTL/LTR

Full Unicode support for Arabic, English, Chinese, Hebrew, Japanese, and all other scripts. Toggle text direction per panel for correct display.
