write real and imaginary parts in text file

[Carreira]

Hi all

I am a rookie in Labview and I have a question.

I want write a .txt file with 3 columns where:

first column is the frequency

second column is the real part of FRF, and

third column is the imag. part of FRF

Can someone help me?

Thanks

You want this:

 

Not this:

Depending on your version of LabVIEW, the 'write to spreadsheet file' should be polymorphic

You can also remove the 'open/create file' function.

The 'write to spreadsheet file' will create a new file if it does not already exist.

Thanks Cory K

I made the changes that you said, but the program still have error because "build array" output is a 2D array of 3 element cluster and the "write to spreadsheet file" input is a 2D array.

How can I make this conversion of data?

Im send my code for better understanding.
