SharePoint supports all types of file formats. You can pretty much upload anything to your directory without a hitch. However, the older versions have issues with particular file types. For example, the following extensions are completely blocked from the 2016 server: • .asmx • .asmx • .svc • .soap • .json • .xamlx Luckily, the current server has no such limitation. As of now, there are no formats and extensions that are banned from SharePoint.
