How to write data into an excel file but keep the original formatting?

How can I write values into my excel file without changing the formatting that already exists. specifically I want to keep the cell formulas and cell colours unchanged. This is what I have so far but it wipes out all formatting:

writetable(ResultMtx,Result_File);

What release are you using? You forgot to enter it for some reason when you filled out the submission form. Yes that was a problem but I believe they fixed it now. Try release r2021a or later. If I recall correctly, it's no longer blowing away my formatting present in an already-existing workbook.
