Problem in making a nested loop with multiple set nodes

[tree]

Hello everyone!

I tried making a workflow, which uses 2 google sheets.

First one - each row = a album, it has a column which has all the urls of the images, and another column called ‘client number’, which has the client’s number to whom each row has to be sent.

Second one - it has ‘client number’ and ‘client email’.

not sure if this can be made more simple, either in the format of the sheets or the workflow

heres the workflow i made so far

Hey,
here i can share an example, in discord the topic get lost.

Basically you try to map a row value(multiple separated by comma, clients), and assign each value to a certain id(client no).

Would be much simpler if you use SQL (postgress for example), but as you can see the Merge node has the posibilty as well.

After the filter you can simply use the loop, and send whatever you need .

Cheers!
