Information about CSV and XLSX file formats
|Full name||CSV - Comma-Separated Values||XLSX - Office Open XML Document|
|File extension||.csv||.xlsx, .xlsm|
|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.||The Office Open XML file formats are file formats that can be used to represent electronic office documents. There are formats for word processing documents, spreadsheets, presentations, and specific formats for material such as mathematical formulae, graphics, bibliographies, etc.|
|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.||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 document, the packages have different internal directory structures and names.|
