Surprisingly, while this format is very common, it has never been formally documented. Additionally, while the IANA MIME registration tree includes a registration for 'text/tab-separated-values' type, no MIME types have ever been registered with IANA for CSV. At the same time, various programs and operating systems have begun to use different MIME types for this format. This RFC documents the format of comma separated values (CSV) files and formally registers the 'text/csv' MIME type for CSV in accordance with RFC 2048. This spec documents the format that seems to be followed by most implementations: 1.) Each record is located on a separate line, delimited by a line break (CRLF); 2.) The last record in the file may or may not have an ending line break; 3.) There maybe an optional header line appearing as the first line of the file with the same format as normal record lines; 4) Within the header and each record, there may be one or more fields, separated by commas; 5.) Each field may or may not be enclosed in double quotes; 6.) Fields containing line breaks (CRLF), double quotes, and commas should be enclosed in double-quotes; 7.) If double-quotes are used to enclose fields, then a double-quote appearing inside a field must be escaped by preceding it with another double quote.", "datePublished": "2005-10-01","creator":[{"@type":"Person","name":"Y.
