Information about CSV and XLS file formats

🔸 File format	CSV	XLS
🔸 Full name	CSV - Comma-Separated Values	XLS - Microsoft Excel Binary File Format
🔸 File extension	.csv	.xls
🔸 MIME type	text/csv	application/vnd.ms-excel
🔸 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.
