Do you need to do it once? Or automatically?

To do it once with not a very large set of data, you can export to CSV.

In Excel and use “Text to Columns” to split the data into columns at the commas

Select each row, copy, paste special, transpose.

Save and re-import.

Other than that, you’d probably need a script I think.

Hey @Matt_Kennedy1

Thank you for your answer!

It is intended to happen automatically, so I a need a script that automates this.

If someone could write me this, I do some leaps of joy.^^

I made this video showing a non-scripting method for creating multiple linked records from a single text field.

You could use the same technique for your list of urls, except instead of splitting out the urls based on the new line character, you would need to split them out based on the comma.

On the other hand, a custom script would be much faster, require fewer fields, and take fewer automation runs.

If you are interested in learning scripting, this would be a good beginner project.

I decided to make a video showing one way of writing a script that does this.

Note that the script in my video will not run as an automation script. However, if enough people view, like, and comment on the video, I will probably make a follow-up video that shows how to convert the script to run as an automation.

Big thank you kuovonne, this helps me a lot. Will try to customize this as my first learn-coding project.
