Alphabetize List
Use this tool to alphabetize a list: paste your lines, choose the order, done. Accented letters are placed by the rules of the page language, and you can remove duplicates and blank lines in the same step.

How it is calculated
The tool puts every line in alphabetical order, the way a dictionary does – optionally by numbers, length, or with duplicates removed. Sorting happens entirely in your browser; your list never leaves your computer.
How the order is decided
Lines are compared with the Unicode collation algorithm using the page language. That is why “Äpfel” sits right after “Apfel” in German and not after “Zebra”. By default upper and lower case do not matter; switch case matching on and capitals come first for the same letter.
- Natural number order: “Chapter 2” comes before “Chapter 10”. A plain character comparison would put “10” before “2”.
- Sort from word no.: with 2, a “First name Last name” list is sorted by last name.
- By number: the first number in a line decides, including thousands separators and decimal commas (“1,200.50”).
- Duplicates: lines count as equal if they differ only in case (and accents, if you ask for that); the first one stays.
To tidy text first, use the text cleaner; to shuffle a list at random try randomize list; and the text compare tool shows the differences between two versions.
Frequently asked questions
How do I sort a list alphabetically?
Paste the items into the box (one per line) and pick “A to Z”. The result appears immediately and can be copied. It works for names, words and keywords alike.
How are accented letters sorted?
By the rules of the page language. In German ä counts as a, in Swedish ä comes after z. The tool follows the collation rules of the language you are reading in.
How do I remove duplicate lines?
Set “Duplicates” to “Remove”. The first occurrence stays, and the number of removed lines is shown.
Why does “10” come before “2”?
Compared character by character, “1” is smaller than “2”. With natural number order (the default) numbers are compared as numbers, so 2 comes first.
Can I sort by last name?
Yes: enter 2 under “Sort from word no.”. The text from the second word on is used, so “Anna Berg” is sorted as “Berg”.
