Imported Text Files Numbers Seen As Text

I have opened a .txt (by right clicking and selecting Open with rather than open from within Excel) file with numbers using the format 1,234,567.00 but in my country we use 1 234 567,00. So I created a macro changing the , into "" and the . into , and it works fine while creating the macro itself (by using the macro recorder) and the numbers shows and behaves like numbers. However, when running the macro on a new file some numbers remain as text whereas others are numbers. Theres is no common string, eg that numbers starting with - (minus) remains text.

It does then not matter if I go to the format function and select number with decimals and thousand dividor - the number still remains as text. I have also tried the suggested multply by 1 but it still remains as text. The only thing that helps is to either double click on the number or use the Konvert text to number. But I would then have to click each number in the whole table which is what I wanted to avoid.
