vbNullString

[Misunderstood]

You could just hit replace all, if you wanted to, but like Spodi says, it really doesn't make all that much of a difference.

Some instances of '""' are needed.

Actually no. It's only used for the Quote = """" And I dont even think that constant is used.

Actually no. I believe some instances of "" are needed, I don't remember which ones, but there was a discussion about this earlier where this came up.
