Enter Line-Break At Specific Location

I know Excel is not the best tool for formatting sentences, but is there a way to insert a Line-Break based on a condition? (Either using Formula or VBA).

The situation is:A fixed-width cell, is a concatenation of 5 strings. Each of these 5 strings is a small sentence of 3-6 words; individually much smaller than the cell-width.2 of these 5 are fixed (one at start, one at the end). The other 3 are results of their respective "IF" formulas.Hence, the final sentence wraps over 2-3 lines.I need the 3rd & 5th sentence (the whole sentence, all 3-6 words of it) to start in a new line, only if they are going to be wrapped into two lines.

So If the wrapping results in:
String1 String2 Stri
ng3 String4 Stri
ng5

Then change it to:
String1 String2
String3 String4
String5
