wiring into a sub-vi

[HereWeGo]

I am attempting to wire the channel names from a nidaq task to the block diagram of the export waveforms to spreadsheet vi for output to file.  How would I do this?  Also, the output of the property node is a 1-D array and when I output to the file I will need a string.  How do I convert from 1-D array to string?  The format into string doesn't seem to work.  The code I have is attached

You first need to provide some information as to what kind of output format you're looking for.

Also, what are you trying to modify with the stock Export Waveforms to Spreadsheet File? You seem to have created a copy of it (though you're not calling it), and seem intent on modifying it for something.

I am trying to output the nidaq channel names along with the daq numerical data to a text file.  Is it possible to wire directly from a the channel names property node into the block diagram of my export waveforms to file vi

You are, imho, making this far too complicated. Instead of modifying the existing VI, you can use a separate Write Text File for the channel names and then call the Export Waveforms to Spreadsheet File later. Just set the append to file to true.
