A web-based CSV cleaner that pairs every cleaning operation with a visual diff view — showing exactly which rows and fields were added, removed, or modified. Users can review changes interactively, undo specific transformations, and export a verified, trusted output alongside a full change log. The tool positions itself not as a cleaner but as a data verification layer.

The explosion of no-code workflows, analytics exports, and AI-generated datasets has put CSV handling in the hands of non-engineers who lack scripting skills to audit transformations manually. Growing data governance expectations in SMBs^? and startups make auditability a real purchasing criterion, not just a nice-to-have.
