myob conversion

Am using Reckon Accounts Plus 2017 Desktop - do not want to use the online conversion service - would perfer to do it myself as there are a lot of tax file codes, accounts, customer information  etc that I have customised in MYOB - is there a downloadable conversion software available?  Alternatively is there a series of imports that can be done easily from a MYOB export (ie accounts, tax file codes, customers, suppliers ... and whatever else would be brought in.

At the moment what I am looking at doing is a customised export/import for each catagory and for the transactions to bring over the data from MYOB but surely there is a quicker way without using the conversion service.
