Information about XLSM and CSV file formats

Name XLSM CSV
Full name XLSM, Excel Open XML Macro-Enabled Spreadsheet CSV - Comma-Separated Values
File extension .xlsm .csv
MIME type text/csv
Developed by Microsoft Informational RFC
Type of format Spreadsheet multi-platform, serial data streams
Description XLSM is the file extension that is assigned to spreadsheets created by Microsoft Excel 2007 and newer. They are saved using the Open XML standard. Just like older version of the Excel spreadsheet, XLSM files can contain tables and worksheets. On top, XLSM files are macro-enabled. They can contain embedded macros that use VBA. 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 As stated above, XLSM files are macro-enabled. This distinguishes the format from XLSX files that are also created by Microsoft Excel. Thus, for Excel to be able to execute the macros embedded in the file, the spreadsheet has to be saved in the XSLM format rather than as a XLSX file. Predecessors of Microsoft Excel 2007 are only able to open XLSM files if they support Open XML components. 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.
