I am having a hard time understanding this line in Step 5. What is being indexed? -> if sheet_data[0]["iataCode"] == "":

@jmorris236 It means if that cell is empty, then execute the code below,

Thank you! I was way too lost in this project. I had a hard time finding my way into tequila API but your code showed me it actually pretty easy.
