I use Patch to drive data into my datasource, which is an Excel table. I pull that data back in to different PowerApps screens. I want to set up a button on one of my screens that clears all of that data out of that table. Any suggestions?
Easiest way is to collect all rows from main datasource into a collection and then use that collection to remove that rows
Put in your button OnSelect property
ClearCollect(RemoveCollection, MainDatasourceName); Remove(ManiDatasourceName,RemoveCollection)
Change the MainDatasourceName with the name of your excel datasource

If you want to clear the excel table you'll need to use a Remove or RemoveIf function
https://docs.microsoft.com/en-us/powerapps/functions/function-remove-removeif
If all you want to do is clear the collected table information in PowerApps, it should be just as easy as doing a Clear(Collection)
If you want to collect fresh info you can do a ClearCollect(Collection, 'DataSource')
See the Clear, Collect, CleaCollect functions here:

Well it worked but...... The first column in my table is "ID" numbered 1, 2, 3... I use this to reference the rest of the data. When I cleared out everything it cleared that too - never thought about that. Now I'll have to reset those numbers every time. Can I reference a Row in Excel instead? I won't have to reset my table all that often but I'm hoping there's a way around this.
@hughrmarks
So why are you trying to reset the table then?
You can also reset the table and look for a highest id in a table where your IDs are stored and continue adding new row to the table you reset with highest id+1
@Sienna I pull data from the table to populate some screens. When I want to start over, I need to clear that data. I'm sure it would be much easier to use a collection for this but I'm finding it very difficult to pull specific tems out of a collection. I suppose I should learn more about them. Thank you for your help.
Collection does sound like a better idea. I have a couple videos that may help at least get you closer. PowerApps Collections and More PowerApps Collections.
Maybe instead of troubleshooting this temp table in Excel, which isn't a good idea anyway, let's try troubleshooting your issues with collections. 🙂
