ok thanks. I take your points, but I still think NI should make this clearer.

I will follow the 'read from text file.vi' example as a template

Why would you follow that example? That makes no sense. The Read From Spreadsheet File will give you what you need in one step, rather than having to put together all the code as seen in that example.

That's like taking a flight from San Francisco over to Hawaii, then to Japan, then to India, then to Italy, then to New York, and then to Las Vegas, instead of flying direct from SF to Vegas.

I know this has been resolved but I thought an example I wrote might clarify for others what the "Read / Write To Spreadsheet" actually does and the file it creates.

I am a beginner so I have to write little bits of code to find out how it acts.
