About the Text Tools
Paste text on top, click one of the 16 buttons, and the result appears in the box below. It is useful for cleaning lists copied from spreadsheets, removing duplicate email addresses, fixing English title case and joining sentences broken by line breaks. If you change the input, the chosen conversion is applied again automatically.
Frequently asked questions
How does removing duplicate lines work?
If a line appears several times, only the first occurrence is kept and the rest are removed. The order of lines is preserved.
How does sorting work?
Lines are sorted in Korean dictionary order, which puts Korean (Hangul) text before English letters, and English letters in alphabetical order. Numbers are compared as text, so 10 can come before 2.
What does 'title case' do?
It capitalizes the first letter of each English word and lowercases the rest. It has no effect on Korean text.
