Convert a formula field into a linked field through an automation

Hi There! I am pretty new on airtable but finding out that it is a really helpful tool for my bussiness

I am preparing (fighting against actually:-)) an accounting table and i want to convert a formula field to a linked field through an automation. I dont have any problem if the formula returns a single string but i am not able to do that when the formula returns several trings separated by commas. I have read here and there that this option ( i mean, to convert a string with commas into diferente links on a linked fill is possible just copying and pasting) But, with the automation, i get a single link instead of several links. ┬┐Do you know why it is happening?

Thanks!

Solved!!! It was a problem of a copy paste. The copy paste on teh formula field was adding blank spaces
