Describe the Issue

I'm running a collection with a csv file to import the many data rows. Some of these fields contain numbers. I'm pretty certain that all of my values in the csv file are saved as strings. But in the Preview, they come up as Auto-Detect, and they get auto-detected as numbers. I can understand that for the fields that have only numbers, even though it is a little frustrating. But the main issue is, that I have a phone number that contains a +, but even this gets detected as a Number, and removes the + from the front. When I change it to String, the + is added back.

Steps To Reproduce

1. Create a CSV file with a value of a phone number with a plus, e.g. +447929601469
2. Select to run a collection
3. Import the CSV
4. Preview the CSV
