○Open: public page gives enough substance to understand the site $Paid: pricing, booking, ecommerce, subscription, or paid access is visible ADAds: visible ad load or ad-supported content ✦Pretty: notable design, copy, craft, or presentation ◆Pro: polished, finished-feeling, serious, or operationally mature ◇Niche: specific audience, workflow, or unusually focused use case ◉Human: personal, local, community, civic, handmade, or real-person signal !Suspicious: scammy, spammy, trust theater, finance fog, or credibility concern

A free set of CSV, PDF, and Excel tools that split, merge, convert, sort, filter, and reorganize files without uploading them.

The unusually broad collection covers practical chores such as deduplicating CSVs, splitting Excel sheets, and deleting PDF pages.
