error when creating a point cloud from an ASCII file (xyz)

I have an excel with xyz coordinates of the terrain. I want to import them in the point cloud tool. I can create an ASCII file (*.xyz) an use the import option.

I created a small test file, with the coordinates (see attached - I had to rename to txt-file to be able to upload it here).

When importing it, it reads the coordinates as expected:

However when trying to create the pod-file, it fails (message center: "Convert Failed"). I read this topic ( Export a POD file into text, in order to create a mesh from the points generated. ) about it but it seems not related to my issue, since I only have xyz defined.

1	2	3
2	3	4
3	4	5
4	5	6
5	6	7
6	7	8
7	8	9
8	9	10
