Information about XLS and CSV file formats

Name XLS CSV
Full name XLS - Microsoft Excel Binary File Format CSV - Comma-Separated Values
File extension .xls .csv
MIME type application/vnd.ms-excel text/csv
Developed by Microsoft Informational RFC
Type of format Spreadsheet multi-platform, serial data streams
Description 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". 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.
Technical details OpenOffice.org has created documentation of the Excel format. Since then, Microsoft has made the Excel binary format specification available to download freely. 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.
