Tutorial Processes
Writing the Labor-Negotiations data set into an Excel file and renaming it
This Example Process shows how the Rename File operator can be used to rename a specified file. For this Example Process you first need a file to rename. 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. A breakpoint is inserted so you can have a look at the Excel file. For further understanding of this operator please read the description of the Write Excel operator.
The Rename File operator is inserted after Write Excel. The file parameter is set to '%{tempdir}/Labor data set.xls' and the new name parameter to 'labor_data_set.xls'. Run the process and the file in a temp folder on your computer which was formerly named as 'Labor data set.xls' will now be named as labor_data_set.xls'.
