REQIF to XLSX conversion => datatypes not preserved

[laurentcabot]

TEST_List_and_CheckBoxes_DataTypes.zip
The attached file contains one column with a list datatype and one column with a check box datatype:

RIF lists are converted to pure text in the Excel file and check box is converted to True / False.
Is it possible to preserve the datatypes during conversion.

If yes, should be also applied to the reverse conversion XLSX to REQIF.

this is "by design" for now.
Excel export is lossy.
A full-feature export would need much more efford ...
