Tutorial Processes

Writing the Labor-Negotiations data set into an Excel file and copying it

This Example Process shows how the Copy File operator can be used to copy a specified file. For this Example Process you first need a file to copy. An Excel file is created by loading the 'Labor-Negotiations' data set with the Retrieve operator and writing it into an Excel file with the Write Excel operator. The file is saved as '%{tempdir}/Labor data set.xls' if this file does not already exist. For further understanding of this operator please read the description of the Write Excel operator.

The Copy File operator is inserted after Write Excel. The source file parameter is set to '%{tempdir}/Labor data set.xls' and the new file parameter to '%{tempdir}/test/Labor data set.xls'. Run the process and two files are created in a temp folder on your computer, the 'Labor data set.xls' of the Write Excel operator and the 'Labor data set.xls' in a separate folder named 'test'.
