Deleting Forms Responses >300

If you would like to edit or delete responses 1-300, you can easily do so by...

1. going to your Form

2. "Responses" tab

3. View Results

4. Choose the response you'd like to change from the drop-down

3. Click the 3 dots (. . .) on the bottom right of the greyed response area

4. "Delete Response" 

If you'd like to edit responses 300+, you're screwed. I've talked with Microsoft Support and as of right now (Aug 2018) you cannot edit response data over 300 submissions. 

You can make an online Excel doc and have your form dump the data into the Excel doc, and that works okay.
