Paste CSV, drag column headers into a new order, hide what you don't need, rename headers, and copy a cleaned-up CSV back out. Quoting, embedded newlines, escaped quotes, and custom delimiters are all preserved.
Drag rows to reorder. Uncheck to hide. Edit the right-hand box to rename a header in the output.
First 20 rows of the reordered output.
Parser follows RFC 4180 with two pragmatic extensions: it accepts \r\n, \n, or bare \r as record separators, and it auto-detects whichever of , ; \t | appears most frequently on the header row when delimiter is set to auto. Quoted fields may contain the delimiter, line breaks, and escaped quotes (""). On output, any field containing the delimiter, a quote, or a line break is wrapped in double quotes with embedded quotes doubled — matching what Excel, LibreOffice, and Postgres COPY ... CSV all expect.
