It is impossible to help you properly here without the correct context — in the absence of which, many of the suggestions you receive may be completely wrong.
It's all very well saying "sur une liste Excel" — but you miust have some idea what kind of installation is being discussed, what the Excel list is for, what line of business the customer is in... all these things may give tiny clues that could help to decide between several alternatives.
Without any information, we are all working in the dark, and you risk having some wildly wrong suggestions leading to potentially serious translation errors. |
