# Data Handling

- [Data Structure](/appizap-workflow-builder-pro/data-handling/data-structure.md): All data passed between nodes is an array of objects.
- [Transforming data](/appizap-workflow-builder-pro/data-handling/transforming-data.md)
- [Use Code](/appizap-workflow-builder-pro/data-handling/use-code.md)
- [Mapping using UI](/appizap-workflow-builder-pro/data-handling/mapping-using-ui.md): Data mapping involves the process of accessing information from preceding data points. This process does not involve altering or manipulating the data, but rather simply making reference to it.
- [Data Item Linking](/appizap-workflow-builder-pro/data-handling/data-item-linking.md)
- [Data Pinning](/appizap-workflow-builder-pro/data-handling/data-pinning.md): Data can be saved during workflow development by pinning it. This means storing the output of a node and using it instead of fetching new data in future executions.
- [Data Editing](/appizap-workflow-builder-pro/data-handling/data-editing.md): Lets you modify pinned data, enabling you to test various scenarios without configuring each scenario and transferring data from your external system.   This simplifies the testing of unique cases.
- [Data Filtering](/appizap-workflow-builder-pro/data-handling/data-filtering.md): Explore data within the INPUT and OUTPUT panels of the node.   Employ this feature as a means to verify the data associated with your node.
- [Data Mocking](/appizap-workflow-builder-pro/data-handling/data-mocking.md): Data mocking involves the simulation or fabrication of data, serving as a valuable tool during the development of a workflow.
- [Binary Data](/appizap-workflow-builder-pro/data-handling/binary-data.md): Binary data refers to data in the form of file types, such as images or documents. You can process binary data in Appizap Workflow Builder workflows.
