I'm attempting to use the super cool Blob template process that @NicoleJ described here.
My problem is that even when Preserve Formatting is checked, background color, borders, and other formatting is lost.
I've seen elsewhere that you have to specify the range, so that's what I've done. I've tried it both skipping and including field names, and every other which way I can figure out. Does anyone know of a solution or workaround?

I've made a simplified example to show the issue, my actual template and data will be a lot more complex once I figure this out! I'm not sure if it's relevant, but my workflow also generates a BAK file for each output spreadsheet when run. The Wait and Block tools seemed necessary to prevent file corruption from writing the data too fast, I believe.
