The UTF-8 character collection set is the most commonly used collection set for the storage of data records in the csv file format. It is worth noting however that csv is not limited to a single character set and indeed can function with other character sets such as EBCDIC or Shift JIS. Each record in a csv file is typically a human readable plain text line delimited by a line break command. Field separations on a single csv record can be achieved using a comma, tab, or semicolon but every record should have the same number of field separations.
The xlsx filename extension is a compressed archive with an xml directory structure. It is specified in the open standard ISO/IEC 29500-1:2012. .xlsx files do not support macros by design, for that, the .xlsm format should be used. A free compatibility update allows older versions of Microsoft Office Excel such as Office 2003 to open .xlsx documents.
