About the CSV Viewer & Editor
Drop in a CSV or TSV file and work with it like a lightweight spreadsheet: auto-detect the delimiter, edit cells and headers inline, add, duplicate or delete rows and columns, sort, search, clean up duplicates and whitespace, see per-column stats, undo any change, and export to CSV, TSV, JSON, Markdown or HTML. Quoted fields and embedded newlines are handled correctly.
