How to read the webextension xml part form an excel file using my office add-in. Is it possible with office.js? I was trying with getFileAsync, but it is not giving the xml. I am using Office-OOXML-EmbedAddin to embed script lab Add-in, which generates the following webextension xml. Is it possible to read the value of SnippetToImport property with office.js
