Microsoft Money Sunset edition imports OFX, QIF files. It also import QBO and QFX files. There are some differences with QIF and OFX import (see below), but overall either QIF or OFX are fine to use for import.
OFX files are Open Financial Exchange files. This is a preferred format for Xero as transactions are presented only in one way.
Convert CSV, Excel (XLS, XLSX), TXT files to the OFX format: CSV2OFX
Convert PDF files (text based) to the OFX format: PDF2OFX
Convert PDF files (text based) to CSV/Excel: PDF2CSV (Use CSV layout Xero or QB Online)
Convert QIF files to the OFX format: QIF2OFX (this is great option to avoid the date format confusion as QIF file may have dates as DD/MM/YYYY and MM/DD/YYYY)
Convert PDF, QIF, QBO, QFX, OFX files to the OFX format or fix a non-importable OFX file: Bank2OFX
OFX format has the reference ID, when QIF does not. Reference ID (when supplied by your bank) allows to skip already imported transactions.
ProperSoft converters support reference ID and if not supplied, generate it to be unique to guarantee the import for all transactions.
OFX files should be created differently for different software (Microsoft Money for Us, non-US, old Microsoft Money 99, 2000, and also other software like Sage).
QIF format supported by Xero. Make sure to use expected date format (based on your country settings). When you use *2QIF converter, select QIF target as "MS Money or other" and set expected output date format

select a QBO or QFX file
