Information about XLSX and CSV file formats

Name XLSX CSV
Full name XLSX - Office Open XML Document CSV - Comma-Separated Values
File extension .xlsx, .xlsm .csv
MIME type application/vnd.-openxmlformats-officedocument.-spreadsheetml.-sheet text/csv
Developed by Microsoft Informational RFC
Type of format Spreadsheet multi-platform, serial data streams
Description The Office Open XML file formats are a set of file formats that can be used to represent electronic office documents. There are formats for word processing documents, spreadsheets and presentations as well as specific formats for material such as mathematical formulae, graphics, bibliographies etc. 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 use of the comma as a field separator is the source of the name for this file format.
Technical details Office Open XML documents are stored in Open Packaging Convention (OPC) packages, which are ZIP files containing XML and other data files, along with a specification of the relationships between them. Depending on the type of the document, the packages have different internal directory structures and names. 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 they may use quotation marks to surround the field.
