Later, in 2013, some of RFC4180’s deficiencies were tackled by a W3C recommendation. RFC7111 describing application of URI fragments to CSV documents. RFC7111 specifies how row, column, and cell ranges can be selected from a CSV document using position indexes. December of the same year. The format dates back to the early days of business computing and is widely used to pass data between computers with different internal word sizes, data formatting needs, and so forth. For this reason, CSV files are common on all computer platforms.
This is because every CSV record is expected to have the same structure. Statistical databases in various fields often have a generally relation-like structure, but with some repeatable groups of fields.
