This workflow provides an educational overview of JSON data types and structures using n8n nodes. It starts with a manual trigger and progresses through a series of nodes that define and explain various JSON data types, including strings, numbers, booleans, arrays, objects, null, and the use of expressions to dynamically incorporate data. The workflow features several sticky notes that serve as tutorials, illustrating key concepts and guiding users step-by-step. It culminates in a final node that pulls all previous data together into a comprehensive JSON object, demonstrating how to combine different data types with expressions. This workflow is ideal for anyone learning JSON, building automation workflows that require complex data handling, or creating educational resources for n8n users interested in data structures.
