Questions
How big a CSV can it open?
Hundreds of thousands of rows work fine; the table shows 100 rows per page so the browser stays fast.
Which delimiters are supported?
Comma, semicolon, tab and pipe are detected automatically. You can export as CSV or TSV.
How does duplicate removal work?
Rows are compared on the columns you tick (or all columns if none). The first occurrence is kept; leading and trailing spaces are ignored.
