thanks for your post and for your support.
You can export the engine’s surface as Tab-Separated Values (tsv) and open the tsv file in excel.
Please export your engine to the FuzzyLite Dataset format using QtFuzzyLite 6:
(1) from the menu bar: File/Export To/FuzzyLite Dataset (FLD)
(2) Choose the options as shown in the image below
(3) open your tsv file in excel.
Let me know if you were able to do it.
