Is there a way to push data into a key schedule from Excel other than the Key Schedule node from archi-lab? That node is great but it only supports strings (at least from what I can tell) which still leaves a lot of manual (error prone) input.
If you have nothing in the Key Schedule insert data rows until the amount equals the count of rows in excel. Then grab all elements (say way as shown above) and set all data to those elements (including key name).
