Developers, data analysts, and content creators constantly deal with lists that need sorting, cleaning, or deduplicating. These operations are trivial in code but tedious by hand ā and opening a text editor or writing a script just to remove duplicates from a list is overkill. Paste your text, pick the operation, copy the result.
Paste any text with multiple lines into the input box. Works with lists, CSV columns, code imports, URLs, and more.
Select Sort, Deduplicate, Reverse, Trim, Remove Empty Lines, or Add Prefix/Suffix. Configure the options for your operation.
Click Process to apply the operation. The result appears instantly in the output box ā click Copy to use it.
