In the previous example of converting the multi-column table into a string, that was the case: a semicolon for records separation and a pipe for column separation: The basics of the conversion are the same as the AddColumns() variant used earlier, but if we use the same formula as above, we dont get the table we want: So we need to extend that formula a bit so that we can split the value from the Title column into the actual value corresponding to the Title column and we need to add another column that contains the ID (which is a numeric value). Why I use this functionSome text strings are hard to write because they include symbols that are a a part of the Power Apps language or other tricky characters.
