Modify export data(replace characters)

magolla

Hi!

(Sorry for my bad english)

I REALLY need help here, i was using datatables and buttons.In the header columns i MUST use " &nbsp ; " for a non-breaking space,thats work really fine in datatable,but when i use excel export button in the .xlsx file the " " is showing!

I need a way to replace him.

In my code this looks this: "Hello&nbsp ;world"
In datatable looks like that : "Hello World" (really good!)
But when i export,in the xlsx file look like this: "Hello&nbsp ;world"

I aprecciate a hand here!
