OfficeJS read old .doc file

Question

I have Word Add-in that is run in Windows Word 2016. This Add-in must use Office.context.document.getFileAsync function from OfficeJs - to get and process all document content on a server side.

Issue: But sometimes I need to open old .DOC files format, then Word is running in "Compatibility Mode" and this function is failed.

Question: Can I somehow convert it to ".DOCX"format on the client side - using officejs? Or at least send ".doc" file as is, mean get a raw binary of file and send to server?

Thanks!

Add-ins built with Office.js do not run on legacy file types such as .doc, .xls, or .ppt. You would need to convert the files to the new format first.
