Data Shuttle or other solution?



I am trying to figure out the best solution to a project. Basically, we have a system outside of Smartsheet that will not connect to Smartsheet (old system) and we do not want to pay to integrate them.

I want to manually upload exports from the legacy system (.CSV files) into a preformatted Smartsheet sheet on a weekly (or monthly basis), so that my preformatted Smartsheet sheets, reports, and dashboards will update with each new data upload.

We have access to Data Shuttle, but I am curious to know the best way solution for this project.

Any and all help is greatly appreciated.
