How to import interpolation functions for complex numbers？

When using the interpolation function and importing data through EXCEL, it is found that COMSOL cannot import data when there is a complex form of data, such as 1+i. So how do I import complex numbers from a file when using the interpolation function?

One column for the real part, one column for the imaginary part.

OK. Thanks for the suggestion. lol But this is really inconvenient, especially when the amount of data is large

I would like to ask. If I want to load discrete pressure field data, in the form of f(x,y,value), is there any better way besides using interpolation function?
Hope to receive your reply

That's the right approach.

I am trying to import data using Definitions -> Functions -> Interpolation. Data is in Grid format and values are complex. The error I get is "Format of data file is not correct". The file in question has been generated in Comsol, so I assume that the issue is due to the complex values. I am not sure how to apply Jeff's suggestion in the case of a grid file. I tried in the case of 1 dimensional data by changing each line from A+Bi to A B but I still get the same error. Any help would be appreciated
