excel.proxyURL String (default: null)

The URL of the server-side proxy which will stream the file to the end user. A proxy will be used when the browser is not capable of saving files locally. Such browsers are IE version 9 and earlier and Safari. The developer is responsible for implementing the server-side proxy.

The proxy will receive a POST request with the following parameters in the request body:

• contentType—The MIME type of the file.
• base64—The base-64 encoded file content.
• fileName—The file name as requested by the caller.
