Alphabetize List

What is an Alphabetizer?

An alphabetizer (or list sorter) takes a messy list and reorganizes it into alphabetical order — or one of several other useful orders. Instead of manually sorting a list of names, keywords, or items, you paste them in and get a clean, ordered list in seconds.

Our alphabetizer goes beyond simple A→Z. It also handles reverse sorting, name-based sorting (by last name), randomizing, removing duplicates, adding numbers or Roman numerals, wrapping items in HTML tags, and joining items with custom separators.

Common uses

• Students — alphabetical bibliographies, reference lists, class rosters.
• Event organizers — seating charts, guest lists, raffle entries.
• Writers & editors — sorting character lists, glossary terms, indexes.
• Marketers — cleaning keyword lists before adding to ad campaigns.
• Developers — sorting config values, environment variables, import statements.
• Anyone — cleaning up a shopping list, a to-do list, or a list of names.

How the actions work

• Sort A → Z — standard alphabetical order, ignoring case by default.
• Sort Z → A — reverse alphabetical order.
• Sort by last name — ideal for lists of full names like "John Smith" or "Marie Curie".
• Reverse order — flips the list without sorting; useful for undoing a change.
• Randomize — shuffles using Fisher-Yates; good for random draws or study order.
• Remove duplicates — keeps only the first occurrence of each item, exact match.
• Add numbers / Roman numerals — prefixes each line with 1., 2., 3., … or I., II., III., …
• Wrap in <li> tags — outputs <li>Item</li> for each line, ready to paste into a <ul>.
• Strip HTML tags — removes all <tag> markup, useful for cleaning scraped content.
• Join with commas — combines all items into a single comma-separated string.
• Trim whitespace — strips leading/trailing spaces from each item.

Options

• Ignore leading articles — when sorting titles, "The Great Gatsby" would sort under G instead of T.
• Case-insensitive — "apple" and "Apple" are treated as the same for sorting purposes.
