An SIE import file (SIE 4I) holds vouchers from a subsystem such as invoicing or payroll, meant to be imported into Swedish accounting software. Fortnox, Visma and Bokio export and import this Swedish standard.
A CSV file is a comma separated values file commonly used by spreadsheet programs such as Microsoft Excel or OpenOffice Calc. It contains plain text data sets separated by commas with each new line in the CSV file representing a new database row and each database row consisting of one or more fields separated by a comma. CSV files are often opened by spreadsheet programs to be organized into cells or used for transferring data between databases.
