I’m trying to extract particular values from an array based on the key. This would be fine if they all shared the same key name and/or I knew exactly how many there would be of them. But I don’t.
Please see attached screenshot of the array I’m trying to work with.
I want to only work with the key values of Photos0, Photos1, Photos2 etc (which could go up to 25). How do I write a formula that minifies the array to only those items?
Appreciate your help.
Hi @Ally_Colquhoun,
Welcome to this community. 
In order to create a new array with only the key as values, you can use the map() function.
https://www.make.com/en/help/functions/array-functions#map-complex-array--key--key-for-filtering---possible-values-for-filtering-separated-by-a-comma--
For example:
{{map(2.array; "key")}}
(Change the array to your array variable.)
Hey! Thanks so much for getting back to me!
The problem is that the key is not always the same. A number is always appended to the key from 0 upwards (depending on how many items there are). So It goes photos0, photos1, photos2 etc…
So my question is how do I target the key (photos) but ignore those annoying numbers on the end?
I was thinking it can be done with one of the other functions available, or even a regex perhaps?
Many thanks
Hi @Ally_Colquhoun ,
In this case, you could use a combination of an array iterator and array aggregator. Where you then apply a filter in between.
I created a small demo…
