I'm using sheetsJs community edition to create multiple excel files and download them all. Usually I generate around 800+ files at once. I'm using plain Js, no framework, it's an internal tool and I need to do it like this.

My problem is this prompts the user with 800+ download dialog boxes unless they manually go to the browser settings and set the excel files to save without asking. But this is not an optimal fix since, for instance, for some users the excel MIME type is not in the applications section of Firefox and there is no "Do this for all files of this type" in their dialog box. just to mention some issues. Chrome won't even bother to download more than 20 files at the same time.

Has anyone worked with sheetsJs and needed to do this before? My code is so advanced and the reports to generate so complex at this point that changing the library comes to be my last resource.
