# system.dataset.exportExcel

> Exports the contents of a dataset as an Excel spreadsheet.

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.
Boolean | `nullsEmpty` | If True, the spreadsheet will leave cells with NULL values empty, instead of allowing Excel to provide a default value like 0. Defaults to False. [optional]

### Returns
**String** - The path to the saved file, or None if the action was canceled by the user.

### Scope
Vision Client
