SUBSTITUTE Function (DAX)
Replaces existing text with new text in a text string.
The text in which you want to substitute characters, or a reference to a column containing text.
The existing text that you want to replace.
The text you want to replace old_text with.
(optional) The occurrence of old_text you want to replace. If omitted, every instance of old_text is replaced
A string of text.
Use the SUBSTITUTE function when you want to replace specific text in a text string; use the REPLACE function when you want to replace any text of variable length that occurs in a specific location in a text string.
The SUBSTITUTE function is case-sensitive. If case does not match between text and old_text, SUBSTITUTE will not replace the text.
