A step by step of exporting a Data Page list to an Excel file using Platform 8.8.2:

1. Create a Data Page list. 

• This example uses a report definition as a source which queries sample data entered in the Data Type record.

2. Create an Excel template file (see a sample attached)

• Reference the data page name and pxResults() followed by a property name.
• Notice that we can stye the Excel template file such as adding a color to the header.  Column D is also set with 'Wrap text'.

Note - it appears that the Excel template doesn't take parameterized data page.  One workaround is to use a Page-Copy step to copy from the data page [parameter] to a temporary activity page, which then can be used in the Excel template.  E.g. {MySampleDataTypeListFiltered.pxResults().pxCreateDateTime}

3. Upload the Excel template file as a binary file in Platform.

4. Create an activity with one step - Call pxGenerateExcelFile

• Parameter 1 = Excel output file name
• Parameter 2 = Excel template name ("excel!SampleDataTypeDataPage!xlsx")
• Parameter 3 = Select DownloadFile checkbox

5. (Unit test) Run the activity to generate and download the Excel output file.
