How can I export the input and output data of all nodes in a workflow at once?
Hi @Xhmza, Welcome!
Although this is a vague question, I assume you wanted to get all of the flow data in the end. For that, consider using the code node for formatively passing down all the data, and you can use that to either send it somewhere or just save it, or you can use the n8n node itself with a get execution operation inside the node.
