So far, you have seen how to build web and mobile applications to interact with data from REST web services. But Oracle also offers another way to interact with this data: using the Visual Builder Add-in for Excel. Using this add-in, your users can simply download REST data into an Excel spreadsheet, work with it, and upload it back to the REST service.
The Visual Builder Add-in for Excel is currently only officially supported for 32-bit versions of Microsoft Excel 2016, but I have found it to work in newer versions as well.
