Hi elyan,
you can create a csv file with the "Write to Spreadsheet File" function. At the first time add a header row in your array and in all other, in which you use the append "true", write only the values to it.

Hope it helps.

Hi elyan,
here is an example for you. It´s a LV71 example so, please change my "Write to Spreadsheet File" function with yours, shipped with 8.x.

Hope it helps.

All you need to do is check if the file exists, and if not, create it and write the header. Here's a quick rewrite of your program. Use an event structure so the loop only spins if needed. If you don't want to write one last record if the stop is pressed, make a seperate event for the stop button.

points that were incorrect or inefficient in your progam:

• You don't have a wait in your loop, so if no button is pressed, the loop will consume all available CPU doing basically nothing.
• 90% of the code in your two cases is the same. Duplicate code belongs outside the case structure.

Hi Mike,

Can you please attach the missing subvi Write to Spreadsheet File_str_private.vi ?

Hi Partha,

it´s only the string part of the "Write to Spreadsheet file.vi", because in LV7.1 the vi has only the dbl instance.
