1. After pasting, a little clipboard will appear at the bottom of the paste. Click on it and select "Use Text Import Wizard"
2. After fixing the first screen you'll see, hit next. At this point you'll see a " with "Text Qualifier" next to it. Change the Text qualifier to {none}.
Then just hit finished. All your quotes will be preserved.
1) put your keyword list in Column B
2) put the " or [ in Column A
3) put the " or ] in Column C
4) copy Column A and Column C all the way down
5) cut and paste Columns A through C into AdWords
The Google system will automatically close up the extra spaces and will consider Column A + Column B + Column C as one term.
If that isn't clear, let me know and I can provide an example.
