Is there an alternative method or something similar?
The idea is to improve efficiency when communicating with the business users. The BA team usually provides business related data in MS Excel which eventually need to be imported into the program. If we can automate even 80% of this information exchange process between the business and technical team, we will be able to minimize errors, and speed up the process of delivering features to the end-users, and be ahead of our competitors.
I have converted some libraries to use in XFA forms, but not this big. Should be easier in Reader DC which supports Uint8Array as well as some other ES5 things like JSON.parse and new Date('yyyy-mm-dd'). We don't have a Blob object, but maybe that would need to change to a Data object anyway, I only had a very quick look.
I'm not sure what I meant by my comment now, might have been thinking it would be clumsy for the end user or difficult to code.
