You might want to export or import the data of your website so you can comprehensively edit it outside of the Workbench. The Export/Import feature can be useful if you are a user with very specific requirements about the structure of your site that you want to organise manually. You can only export, import, and restore a site archive if you’re a subscribed user.
Exporting from the Workbench lets you download an Excel spreadsheet containing all the website data you have already built on the Workbench. You need to have Microsoft Excel installed to read the Excel file, then you can use it to edit your site data offline. You can then import an edited spreadsheet to update your site data on the Workbench.
