Hello,
One of the modules returns the following string → “[https://fileupload.com/some-file.png](https://fileupload.com/some-file.png)”.
How can I convert it to this array using Make built-in functions?
```js
[{ url: "https://fileupload.com/some-file.png" }]
```
This is the format expected by Airtable in file column.

Just concatenation will work. Create a string literal with the placeholder for your file variable.
The notation in the text will notify the api that you’re sending an array. It’s just text!
So
`[{ url: "" }]`
And put it inside the body you are sending to another api call.
