More about the Text Line Deduplicator
Merging a few exported lists together, email addresses from two signup forms, URLs pulled from separate crawl reports, log lines collected from different runs, almost always introduces exact repeats, and simply sorting the combined list to spot them reshuffles everything into an order that no longer matches how the data actually arrived. This tool removes exact duplicate lines from a block of text while keeping every remaining line in its original order, based on where each one first appeared rather than resorting the whole list. Useful for merging two exported lists and removing exact repeats without scrambling the original order, cleaning up a combined URL list before a crawl without needing everything re-sorted, or deduplicating log lines from multiple files while keeping their original sequence intact.
