Import automation of Excel File to Knime Workflow

Hi! I was just wondering if it is possible or if has anyone tried to automate the import of raw Excel file data to the Knime workflow using Powershell. Since my raw data and output report are done daily I was thinking of automating it from importing the raw excel file in the workflow, and, running the workflow at a certain time (scheduler). I hope you can help me and Thank you in advance for your support and inputs!
