Import of temperature data into COMSOL

Dear all,
I need to import the temperature for every element from another simulation into COMSOL 5.2. The other software (SigmaSoft) allows to export the calculated temperature information as .txt (see small extract below) or .inp format.
Now I don't know how to feed COMSOL with one of these files.
What would be the best solution to transfer the temperature data into COMSOL? The only way I found sofar is the interpolation function.
How do I need to format the file so that COMSOL is able to handle it? So far I only managed to get a .txt file which is structured in the way you can see in the extract below.
I hope there is anyone who can help! Thanks alot!
Best regards,
Maximilian

Create csv/txt file with columns x, y , y and T values.
Create the interpolation function reading from file in model node. Check the argument values from spatial coordinates. In initial values or boundary or domain temperature, type the function name. There will no need to pass the arguments.

Thank you very much! I tried what you suggested, but I can't get where I want to. When I plot the temperature COMSOL shows a block with the interpolated temperature (screenshots in the attachment). Somehow I'm not able to plot the temperature only at the part section.
What I did so far:
- Create the part in COMSOL
- Mesh part
- Export mesh to another Software
- Mapping of the temperature results onto the mesh
- create .txt-File with x,y,z,T Data
- Import .txt-file via Interpolation
I expected that COMSOL only plots the temperature inside the part, based on the coordinates it is getting from the mesh/Excel-File.
I would be greate if you or someone else could help me with this!
Thanks...
