As soon as you actually have working hyperlinks in your spreadsheet cells, it’s no longer about any external ‘data’.
Hyperlinks as parts of texts contained inCalc cells are inserted in one specific way.
What I offered as a possible solution should definitely work in the demo if you permitted the execution of document macros when loading it. However, it can’t be used from that location for a different document. To get (try) it working there, you need to copy the code (3 pieces) into a module of your local ‘Standard’ library for Basic scripts.
Note: The solution follows the concept of the tool >Data>Text to Columns...
, and requires that right of the column to split there are sufficiently many unused columns to accept the results produced by the split.
Though the solution isn’t “final”, its results should easily be usable.
Without rsorting to custom code there will (imo) not be a solution for your problem.
On the other hand: If the import of the links you want can be done one by one with a reasonable expenditure in time - why not?
For me writing the code was (a bit of) fun and an opportunity to learn something again.
BTW: What you actually wanted precisely is still unclear. Equip your next question with more detailed information, please. And if you are asked to supply an example, please simply do so.
