Mapping should work when importing xlsx file

[D365Ideas_Admin]

Currently exporting and importing xlsx file is supported but it doesn’t do any ‘mappings’.
If you change the file from xlsx to csv, mappings work but it would be great that if we don’t need to change xlsx file to anything at all.

Mapping should work when importing xlsx files.
