Help on fonction Write to spreadsheet file

[Nico_AT]

Hello,

I come on this forum to find a solution for my issue.

I have made a VI which acquires an input voltage and where the user can modify some parameters.

For each iteration of my while loop, I want to save the data in a csv file that's why I'm using the fonction Write to spreadsheet file.

But when I want to use this saved datas in csv format with Excel, the data were saved in string format so not a numeric. My purpose is to have some numerical datas and not strings because I can't do graphics or calculs.

As you can see on the csv saved file, only the iterations of the while loop (column C) are in a numerical format.

Here is my problem, thank you in advance for your help

Looks like you're using regional decimal signs, try "%.;.3f" as format

I have forget to thank you.

My issue did not come from this but I've found a solution with the vi Write to TDMS file.

In fact this vi was more appropriate for this kind of applications
