Line Tools

The Line Tools give you a small set of operations for cleaning up pasted text: sort lines alphabetically, remove duplicates, trim leading and trailing whitespace, drop blank lines, reverse the order, or shuffle the lines. You can chain these on a block of text without opening a heavy editor, which makes the tool ideal for tidying a list, normalizing a dump, or preparing data before you paste it into a file or a spreadsheet. It is a fast utility for everyday text cleanup, and it runs entirely in your browser. A surprising amount of day to day work with text is mechanical cleanup rather than real editing, and that is what this collection of line operations is built for. Sorting a list alphabetically, removing duplicate entries, trimming stray whitespace from the ends of lines, deleting blank rows, reversing the order, or shuffling a set are all trivial individually and tedious to do by hand in any quantity. The useful pattern is to chain them: take a messy dump, sort it, deduplicate it, trim it, and drop the blanks, and what was a list of a few hundred noisy lines becomes something you can paste into a configuration file or a spreadsheet. Doing that inside a text field rather than launching an editor is the whole point, since it removes the overhead of opening a heavier tool for a task that takes seconds. Typical sources are exported identifiers, a column copied out of a report, a log excerpt, or a set of values collected by hand. Applying the operations in sequence and reviewing the intermediate result keeps the process predictable, and everything runs in the browser so the data stays on your machine.
