External Mass Updates

Hi! I am working with an inventory style Smart sheet, that tracks the location of monitors and desktops. i.e is the computer checked out to an employee, or is the item available to be shipped. I am "checking out" assets in groups of 50 at a time, through excel as this is faster than a one-by-one search in Smartsheets. My ask is this: Is there a way to take the information from Excel and upload the data to Smartsheets to update the assets that exist here? Thank you in advance for any guidance that can be provided!
