I am actually a student in France and i have to import a csv file into an existing powershell worksheet with powershell. The first file have a list of differenst softwares with their time of use and the number of times they were launched. (https://www.noelshack.com/2019-07-2-1549966301-zav.png) Mai = May, Avril = April, Cumul = Total of all the months.
In the second file, I have only January and so I have to put it in the first file like the others months. (https://www.noelshack.com/2019-07-2-1549966403-zav2.png) There is also softwares that they are not in the first file so I have also to add them.
Thanks for your help.
