I upload all documents to Zoho Books, especially regarding vendors, including their "official" invoice (the vendors send their official ones to us) and our payment slips (proof of payment to them). 

I need to be able to export all these files every now and then for Auditing and other uses, but there is no option I've found. Ideally, for my use case, they would be exported in a ZIP file, where there would be folders per vendor or per accounting category, and inside each folder I would find many PDF files representing the attachments I have uploaded to Zoho. Is this even remotely possible, via a custom script or something like that? 

Thanks
