I have a web based application & I want to open a Microsoft word file within my application (IE browser), edit the document & save the changes & then export it back to .doc
How can LibreOffice help me in this integration ?
If it doesn’t work with latest version and the plugin being enabled in LO settings and computer rebooted, it’s for a good reason, and for that reason also you should give up on IE, that utter junk and security risk. Same for Edge.
