Transfer from NCH to Zoho books

Transfer from NCH to Zoho books

We are using NCH inventoria as a stock management and its syncing with NCH express invoice for invoices and quotes, payments. And now we need to switch to zoho books, i only exported the clients as csv file and imported into zoho and it worked fine. The problem is there is no option to export items, quotes, invoices, payments to csv or xlsx only can export as pdfs and the backup files. The question is there any way to transfer/export the data from inventoria and express invoice to zoho?
 Thanks
