# system.dataset.exportCSV

> Exports the contents of a dataset as a CSV file.

This function is used in **Python Scripting**.

## Description

Exports the contents of a dataset as a CSV file, prompting the user to save the file to disk. To write silently to a file, you cannot use the dataset.export* functions. Instead, use the `system-dataset-toCSV` function.

## Client Permission Restrictions

`system.dataset.exportCSV(filename, showHeaders, dataset)`

### Parameters
Type | Parameter | Description 
------- | ------- | -------

Boolean | `showHeaders` | If true, the CSV file will include a header row.
Dataset | `dataset` | The dataset to export.

### Returns

### Scope

## Code Examples

```python title="Code Snippet"
# This snippet would prompt the user to save the data currently displayed in a Table component to a CSV file, and would open the file (in an external program, presumably Excel) after a successful save.
  
table = event.source.parent.getComponent("Table")
filePath = system.dataset.exportCSV("data.csv", 1, table.data)
if filePath != None:
    system.net.openURL("file:///"+filePath.replace('\\','/'))
