 ### Liquid syntax
 The liquid syntax function allows you to transform event data with fine-grain control before it reaches cloud-mode destinations using the LiquidJS templating language. Use Liquid templates to clean, format, or conditionally transform data such as user properties, timestamps, or event metadata to meet the requirements of your downstream tools. Liquid templates are applied in the Mappings tab of your Segment workspace, ensuring seamless integration with your event pipeline.
