Hi josi,

what does the cluster contain?

Which data format/layout do you need in your CSV file?

[josi_ocroch]

 it contains 2 double and 1 array

Hi josi,

unbundle the cluster, prepend the scalar DBL values in front of the array.

Do this for each cluster and you will get a 2D array. Save that 2d array in your csv file…

I would use a FOR loop to create an array of strings, an element for each line that goes in your file.  Format Into String would be useful here.  Then use the Write Text File to actually write to the file.  Open/create your file before your loop and close it after the loop.

You need to wire a True to the Append to File input of Write to Spreadsheet File.vi. As you have it configured, it overwrites the old data on every iteration of the while loop.

Turn on the context help window to get more information.

You haven't wired the y array to anything. There's also no real reason to convert everything to strings. You can write all as dbl.

i did the conversion because i wanna add another sring with the names of the colums

Ok, stop using the Write To Spreadsheet File VIs.  Use the actual File IO API.  This way you can create the file, write the header data, write data continuously in the loop, and then close the file after the loop.  It will make things a lot simpler and a lot more efficient.

There is also no need to wire up the N on the FOR loop since you have an autoindexing tunnel that will tell the loop how many times to iterate.
