How to use this tool
Pick one operation. Duplicate removal keeps the first occurrence. You can apply another operation by copying the output back into the input.
A quick example
basil, mint, basil on separate lines becomes basil, mint.
Supported formats & limitations
Duplicate matching is case-sensitive and preserves spaces. Sorting uses JavaScript’s Unicode code-unit order, not a locale-specific dictionary. Empty-line removal also removes whitespace-only lines.
