Information about CSV and XLS file formats
|Full name||CSV - Comma-Separated Values||XLS - Microsoft Excel Binary File Format|
|Developed by||Informational RFC||Microsoft|
|Type of format||multi-platform, serial data streams||Spreadsheet|
|Description||In computing, a comma-separated values (CSV) file stores tabular data (numbers and text) in plain text. Each line of the file is a data record. Each record consists of one or more fields, separated by commas. The comma as a field separator is the source of the name for this file format.||Microsoft Excel, up until 2007 version used a proprietary binary file format called Excel Binary File Format (.XLS) as its primary format. Excel 2007 uses Office Open XML as its primary file format, an XML-based format that followed after a previous XML-based format called "XML Spreadsheet".|
|Technical details||The CSV file format is not standardized. The basic idea of separating fields with a comma is clear, but that idea gets complicated when the field data may also contain commas or even embedded line-breaks. CSV implementations may not handle such field data or use quotation marks to surround the field.||OpenOffice.org has created documentation of the Excel format. Since then, Microsoft has made the Excel binary format specification available to download freely.|
