Find nth occurrence of a string

[gv445]

Hi folks,

I have been trying to find any resource that would explain how to get nth occurrence of a string in Power Query and this seems no easy task. There are lots of examples how to find nth character, but I am looking for formula that will find second occurrence of "---" in the following example string:

123---gg---QwQ+++111+++---mmm---

Basically my formula(function) should return 8 in this example. Would be gratefull for any ideas.

Actually this is fairly easy as Text.BeforeDelimiter offers you the choice to control the no. of occurence of the delimiter (on 0 basis. Hence, for 2nd occurrence, you will have to use 1). Use below formula. This would give the result of 8.

= Text.Length(Text.BeforeDelimiter([Column1],"---",1))
