RFC 4180 documents a common CSV format, but CSV implementations still differ. Always check the importing service’s specification.
| Item | CSV | TSV |
|---|---|---|
| Delimiter / 区切り | , | TAB |
| Registered media type | text/csv | text/tab-separated-values |
| Quoting | "field" | Usually optional / implementation-specific |
| Embedded delimiter | Quote field | TAB handling depends on parser |
| Embedded quote | "" inside quoted field | Parser-specific |
| Line break | RFC 4180 documents CRLF | Often LF/CRLF in practice |
