# Converter

The Converter step transforms data into a different format (e.g., JSON → CSV, JSON → XML, JSON → Parquet). This is useful when preparing data for exports, analytics, or other APIs.

**Example definition**

```
StepName = convertInput  
ConversionType = JSON_PARQUET  
Source = {{input}}  
Settings = Default  
```

This means:

* The step is named `convertInput`.
* Input data (`{{input}}`) will be taken from the previous step.
* Conversion type is set to `JSON_PARQUET`.
