  In **ThingsBoard**, **Data Converters** are components used to transform incoming or outgoing data between different formats, typically to convert raw telemetry data from devices into a structured format that ThingsBoard can understand, or vice versa.
++**In this section, you will create a universal uplink data converter for all Dragino NB-IoT devices. The uplink decoder converts any MQTT message coming from a device into key-value pairs that can be used to display and visualize data using various widgets on the dashboard**.
