Text and list dedupe

Choose the rules that define the result

Choose what counts as one item

Start with Lines, switch to Unicode word tokens, or split one list with a comma, semicolon, space, tab, new line, or literal custom delimiter.

Choose how values match and which copy is kept

Ignore case, trim outer whitespace, remove empty items, and keep the first or last matching value according to the visible options you enable.

Choose the result view

Result keeps one value for each distinct match, Repeated shows values found at least twice, and Once only returns values that appear exactly once.

A general workflow for text and lists

1

Paste text or one list

Use the general page when the input boundaries or matching rules still need to be chosen.

2

Set split and matching rules

Select Lines, Words, or Delimiter, then adjust case, whitespace, retention, and sorting only when needed.

3

Review and copy the right view

Check the counts, then copy the distinct result, repeated values, once-only values, or a counted report.

When should I use this general page?

Use it when you need to choose whether the input contains lines, words, or delimiter-separated items. For a fixed one-item-per-line workflow, use the dedicated Remove Duplicate Lines page.

Is my text uploaded?
