Hello Aniket, and thanks once more for the answer.

I found the solution to my problem : 

My windows regional format was not suited to the add-on. 

Instead of writing '.' for my decimal numbers, and ";" for list separation, i had ',' forboth decimal and list separation, so the extension wrote both of those two informations using the same character, making the output file completly out of shape. 

I changed this going to windows config panel => Region => Personalize format => Advanced parameters 

My file was shaped as expected afterward. 


Thanks once more for your help.
