Import CSV Into Pabbly?

I'm new to Pabbly and searched the forum but couldn't find anything. How do I import a spreadsheet into Pabbly so I can run the iterator module?

Youn need to pass CSV data as JSON Array to pabbly webhook.

OR

If you can use google sheet use Get Rows action of Google sheet in pabbly to pick rows required in JSON array format by turning off simple response.
