Export Sale Orders then Importing Invoices

Export Sale Orders then Importing Invoices

I want to Import Invoices to create multiple invoices for sales orders that I have in Zoho Inventory.

Can I create an Export CSV file of my Sales Order, modify the file to match the Import Invoices format, then import to Invoices?

If so, which fields will I need to keep in the CSV file?
I see that only 4 fields are marked as mandatory when Importing Invoices, but I am assuming that I will need several non-mandatory fields to properly create an invoice.
