pretty-csv

pretty-csv renders CSV (or TSV) files as aligned, bordered tables in the terminal.

• Auto-fits table width to the terminal (truncates with …).
• Three border styles: ascii, box, dos.
• Transpose mode: show each record as a vertical key-value block.
• Column selection: display only specific columns.
• Optional row separators between data rows.
• Right-align selected original columns (useful for numeric CSV fields).
• For standard comma-separated CSV input, parsing now fully implements RFC 4180.
• Supports quoted fields, including delimiters inside quotes.
• Supports embedded CRLF inside quoted fields.
• Unescapes doubled quotes in quoted fields.
• Rejects malformed quoted fields and rows with inconsistent column counts.
