Read string, convert to collection, write back to string

Posted on by eltibu

My scenario is as follows.

I have a SP list with a column that is single line text, used to save down Tags/Labels. These are saved separated by semicolons.

In the PowerApp, I now want to read these strings, split them and put them into a collection, then have the user edit said collection. Then save back down as a string separated by semicolons.

I find it relatively simple to write something such as

ClearCollect(colText,Split("Test1;Test2;Test3",";"))

to create my collection and to subsequently work with it. How do I best initialise this collection creation though, so that the user can right away work with the collection?

This is all done within a form, I'm looking to replace the text input presently in place in there.

Hope I've expressed myself clearly enough and look forward to any ideas on how to best to this.

Hi @eltibu ,

Please try this:

ClearCollect(colText,Split("Test1;Test2;Test3",";"));Clear(colText)

The clear function will delete all items in the collection and keep the column.

Best Regards,
