This is very doable, if you haven’t already figured it out I have some examples from a project I did recently. The extract dyn file will write an excel file from the sheets and custom properties. The import file will take the same excel file and write it back in to the sheet set.
Word of warning, large sheet sets can take some time to process the import, depending on the amount of data your pushing.
