# AWS::QuickSight::DataSet DataPrepConfiguration
<a name="aws-properties-quicksight-dataset-dataprepconfiguration"></a>

Configuration for data preparation operations, defining the complete pipeline from source tables through transformations to destination tables.

## Syntax
<a name="aws-properties-quicksight-dataset-dataprepconfiguration-syntax"></a>

To declare this entity in your CloudFormation template, use the following syntax:

### JSON
<a name="aws-properties-quicksight-dataset-dataprepconfiguration-syntax.json"></a>

```
{
  "[DestinationTableMap](#cfn-quicksight-dataset-dataprepconfiguration-destinationtablemap)" : {Key: Value, ...},
  "[SourceTableMap](#cfn-quicksight-dataset-dataprepconfiguration-sourcetablemap)" : {Key: Value, ...},
  "[TransformStepMap](#cfn-quicksight-dataset-dataprepconfiguration-transformstepmap)" : {Key: Value, ...}
}
```

### YAML
<a name="aws-properties-quicksight-dataset-dataprepconfiguration-syntax.yaml"></a>

```
  [DestinationTableMap](#cfn-quicksight-dataset-dataprepconfiguration-destinationtablemap): 
    Key: Value
  [SourceTableMap](#cfn-quicksight-dataset-dataprepconfiguration-sourcetablemap): 
    Key: Value
  [TransformStepMap](#cfn-quicksight-dataset-dataprepconfiguration-transformstepmap): 
    Key: Value
```
