I'm trying to import a spreadsheet with dates and export it again. But the cell reads ### in the exported file. It's shown in the screenshots. This is my code.
SetDirectory[NotebookDirectory]; file = Import["import.xlsx"]; Export["export.xlsx", file];
Is there some way to get this working? I'd like the export file being the same as the import file.
I was trying this with Mathematica 12 on Linux and Mathematica 11 on Windows.
Here's the import file.
Thanks a lot!
