Comma-separated values (CSV) is a text file format that uses commas to separate values, and newlines to separate records. A CSV file stores tabular data (numbers and text) in plain text, where each line of the file typically represents one data record. Each record consists of the same number of fields, and these are separated by commas in the ...
The enumeration or ideographic comma (U+3001 、 IDEOGRAPHIC COMMA) is used in Chinese, [37]: 20 Japanese punctuation, and somewhat in Korean punctuation.
