Convert Variant Array to String

Question

I am trying to take a variant variable and convert it into a string so that I can run a split function on the data. However, whenever I try to redefine the variant I get a type mismatch error. I have used the CStr(), Str(), and ToString functions. None work.

Anything I am missing?

Function FlatLine(ByVal lines As Variant)

Dim flat() As String
ReDim Preserve flat(i)

For i = 0 To UBound(lines)
    flat(UBound(flat)) = lines(i)
    ReDim Preserve flat(LBound(flat) To UBound(flat) + 1)
Next i

Dim flat2 as String
flat2 = Cstr(flat)

^ errors there.

Answer 1

The for is useless, as far as I can see. Better ReDim flat and generate flat2 as below

ReDim flat(UBound(lines))
flat2 = Join(flat,"|")

in fact, given that lines is coming in as ByVal you could probably

flat2 = Join(lines,"|")
