Instructions
Introduction
Automatically identifies and deletes duplicate lines in text, supporting options such as preserving first occurrence, case-sensitivity, and ignoring whitespace.
Steps
Paste the text that needs to be de-duplicated, check the de-duplication option (such as case-sensitive, ignore blanks), click De-duplicate, and copy the result.
Notes
The order of the rows after deduplication remains the same; if you want to sort at the same time, please use it with the sorting tool.
