在Golang中修改CSV文件的内容

My problem is that I have a csv file with a content. Like:

Number,Name
1,First
2,Second
3,Third

In this table I want to change one of the value with golang. For example obtain this content:

Number,Name
1,First
2,Change
3,Third

The only thing I found is to add value in the csv file and not change it. How implemement it?

Thanks in advance!
