Used for exporting and exchanging data among various databases. It is also used in retrieving database data. In a crux, it depends upon your application for which you are using the data file.
The TSV file format is a more constructive and a more technically sound format. Whereas CSV is more prevalent and is being used more than its counterpart. Consider the data in this table:. In Field-2, the first value contains a comma, the second value contains both quotes and a comma. Here is the CSV representation, using escapes to represent commas and quotes in the data.
In the above example, only fields with delimiters are quoted. It is also common to quote all fields whether or not they contain delimiters. The following CSV file is equivalent:. Furthering this confusion, it is somewhat common to have data files using comma as the field delimiter, but without comma, quote, or newlines in the data.
No CSV escapes are needed in these files, with the implication that traditional Unix tools like cut and awk can be used to process these files. Such files are sometimes referred to as "simple CSV". They are equivalent to TSV files using comma as the field delimiter. Traditional Unix tools and tsv-utils tools can process these files correctly by specifying the field delimiter. However, "simple csv" is a very ad hoc and ill defined notion.
A simple precaution when working with these files is to run a CSV-to-TSV converter like csv2tsv prior to other processing steps.
Such data cannot be reliably processed by Unix tools like sort , awk , and cut. The csv2tsv tool in tsv-utils avoids escapes by replacing TAB and newline with a space customizable. This works well in the vast majority of data mining scenarios. For example:. Approaches that generate CSV escapes will enclose a number of the output fields in double quotes. Note If the text file has a header row row that identifies the name of each column of data , click the check box for My data has headers.
