Keep decimals when converting from "," to "."

[cje]

We have a system which is sensitive to decimals when importing a csv statement;

• the decimal separator need to be converted from our standard “,” to “.” and
• every converted number need to have 2 decimals.

When changing decimal separator from standard “,” to “.” the decimals which are 00 disappear.

Is there a way to keep 2 decimals, whatever number, when changing the decimal separator?
If not, is there a CONCATENATE formula which I can use to add the missing zeros after converting?

Thank you for any suggestions.

I found an answer;
I just selected the cells and changed the language under format.
