Reading File of Complex Numbers

Question

I have a text file "IQ256.txt" with the following format (one complex pair per line):

-23636.100 13359.055I  
-25478.040 9342.004I  
-26637.370 5257.033I  
-27184.020 1087.021I  
-27069.778 -2976.033I  
-26338.223 -6446.660I  

which I want to import into Mathematica for spectral analysis. I'm having trouble doing this. Can someone help this newbie?

Answer 1

This interpreter works DelimitedSequence["ComplexNumber"], you can use it with SemanticImport:

SemanticImport["IQ256.txt", DelimitedSequence["ComplexNumber"]]

Or interpret the string directly:

Interpreter[DelimitedSequence["ComplexNumber"]] @ Import["IQ256.txt"]

Answer 2

E.g:

Total[ToExpression[Import["asd.txt", "Data"]], {2}]
