Migration compatibility from ANNA to XERO

I am migrating my accounts from a package called ANNA to XERO and need some help as the files aren't compaitable. The files need to be converted in excel.csv so the ANNA data in each coloumn match the Xero template to put the info in the correct order. I need the initial files converted but would like a program/formula so I can convert future files. I can provide a sample template from Xero and the ANNA data that needs to be manipulated.

File attached, so top header is exported from Xero template. Second line is the ANNA data format. About 15 coloumns that need to be best matched to the fields available.
