Hi All,

I have several unwanted collections in my app, which I used for testing. Is there a way to remove them from the app?

Thanks in Advance

Hi @Skybluekid,

Yes, you can permanently remove test collections. Have you try the following already?

Open your canvas app in edit mode

Go to App > OnStart (where collections are usually created)

Look for lines like ClearCollect(colName, ...) or Collect(colName, ...)

Delete the entire line that creates the collection - Save the app - Preview to make sure nothing breaks

If It's Used in Multiple Places

Click the search icon (magnifying glass) in Power Apps Studio

Search for your collection name

You'll see all screens, controls, and formulas using it

Update each reference (like changing a gallery's Items property to a different data source)

Then delete the collection definition

Using Clear(colName) only empties the data. It doesn't remove the collection. You have to delete the formula line to fully get rid of it.

Once deleted, the collection won't show up in File > Collections anymore.

Hello @Skybluekid,

You can easily find all collections in the app by going to Variables -> Collections. If a collection is no longer needed, just remove the Collect() or ClearCollect() formula that creates it.

Once you have the list, you can also use the Search tab and search by the collection name (for example, c_). The search results will list all usages, and clicking on the collection name will automatically take you to the place where it’s used.
