Hi,
I’m easily able to return the value of a string in an array by it’s index position with the FIND function.
e.g. if array = [“hello”,”World”]
FIND(array,1) = “hello”
However, i’m struggling to understand how to do the inverse - finding the index position of a string in an array by the value of the string:
e.g. if array = [“hello”,”World”]
‘STRINGFIND’(array,”hello”) = 1
I’m sure this is quite simple and I’m just missing the correct function.
Thanks!

Find index position of a string in an array

+5Hi JoshJefferis!
At this time, we actually do not offer an out-of-the-box function for finding the index position of a string in an array. There is a very “hacky” way to do this though:
=ASARRAY(FILTER(MAP(@Haystack, x => IF(x = @Needle, x.index, NONE)), x => x != NONE))[1]
Note that this returns #ERROR! if an item isn't found. It can be wrapped in IFERROR to provide a default value like -1.
Also, you posted in the developer forum, so I am wondering if there are other tools at your disposal. Are you building an extension using our Extension API? If so, we may have a few other levers. If not, then the formula above is the best solution available we can think of.
Thanks!
Ian
