We've pushed an update to EZ Exporter adding new pre-computed shipping-related fields to Shopify order data exports.  This eliminates the need to use complex formulas to parse the shipping_lines and refunds fields to figure out the current shipping prices after order edits and refunds.

The following fields are now available:

• shipping_lines.current_total_price - Shipping Lines Current Total Price (type: number). The current total shipping price (before discounts and taxes) for this order after order edits and refunds.
• shipping_lines.tax_lines.current_total_price - Shipping Lines Tax Lines Current Total Price (type: number). The current total of all tax line prices for all shipping lines after order edits and refunds.
• refunds.order_adjustments.shipping_refund.total_amount - Shipping Refund Order Adjustment Total Amount (type: number). The total amount refunded for shipping (excludes taxes). Can be negative.
• refunds.order_adjustments.shipping_refund.total_tax_amount - Shipping Refund Order Adjustment Total Tax Amount (type: number). The total tax amount refunded for shipping. Can be negative.

The shipping_lines field, which is a list of shipping line attributes, also now includes a field called is_removed (True or False value) for each shipping line.  This lets you know which specific shipping lines were removed from an order via an order edit.
