Your second line will not be correctly split. If you want to use quotation mark ( ") inside your string, you need to double it. Since your string consists only of quotation marks, it looks like this:
- Sign of the quotes to start the line
". - Double quotation mark, which is a single row within the quotes,
"". - Trailing quote
".
In short:
s1 = Replace(s1, """", "")
