I am trying to remove commas inside double quotes from a csv file in notepad++, this is what I have:

```
1070,17,2,GN3-670,"COLLAR B, M STAY","2,606.45"

```

and I need this:

```
1070,17,2,GN3-670,"COLLAR B M STAY","2606.45"

```

I ma trying to use notepad find/replace option with a reg exp. pattern.
I tried all kind of combination but didn't manage to do :( The file contains 1 million rows.

After whole today I am not anymore sure if a simple regex can do? Maybe I should go with a script...python?
