secondary: text, spreadsheet, data

csv files are made up of a single spreadsheet with any number of rows and columns. Columns and rows create cells where individual data is stored. E.g., a 5 column by 5 row csv would have 25 data cells (5 * 5 = 25). Columns generally have a header row with column names. Some programs will use the first row automatically as header information.

The internal structure of csv files is incredible simple. A csv is made up of records (lines). Each record consists of values (any characters) separated by commas. The end of each line contains a Carriage Return Line Finish (CLRF; created by pressing the Enter/Return key). The first line is optionally a header line with information about each column. A final CLRF is optional at the end of the file.
