What three things does it clean up specifically?

Whitespace (trimmed from each line), empty lines (dropped entirely), and duplicate entries (removed, keeping the first occurrence).

Is this the same as chaining multiple text tools together?

It does the equivalent of remove-extra-spaces, drop empty lines, and remove-duplicate-lines all at once, saving you from running three separate tools in sequence.

Does it preserve the original order of remaining items?

Yes, the order of surviving lines is preserved, aside from empty lines and duplicates being removed.

Does List Cleaner upload my files to a server?

No. List Cleaner runs entirely in your browser using on-device processing, your files never leave your device.

About this tool

A list pulled together from multiple sources often has messy whitespace, blank entries, and duplicate items mixed in, and cleaning all three issues by hand across a long list is genuinely tedious. This tool trims whitespace, drops empty lines, and removes duplicates from a list in one pass, giving you a clean, usable list without three separate manual cleanup steps.
