system.dataset.exportExcel

This function is used in Python Scripting.

Description

Exports the contents of a dataset as an Excel spreadsheet, prompting the user to save the file to disk. Uses the same format as the system.dataset.toExcel function. To write silently to a file, you cannot use the dataset.export* functions. Instead, use the toExcel() function.

Client Permission Restrictions

This scripting function has no Client Permission restrictions.

Syntax

system.dataset.exportExcel(filename, showHeaders, dataset, [nullsEmpty])

Parameters

Type	Parameter	Description
String	filename	A suggested filename to save as.
Boolean	showHeaders	If true, the spreadsheet will include a header row.
Dataset / List[Dataset]	dataset	Either a single dataset, or a list of datasets. When passing a list, each element represents a single sheet in the resulting workbook.
