In EZ Exporter, you can add the condition below under Custom Filters to only include online/web orders in your export:

• Source Name is equal to any web,580111

This will filter orders whose source_name value is either "web" or its corresponding channel ID of "580111".

In most cases, the value of the source_name field will be "web", but we've seen a few instances where the Shopify backend sometimes uses its channel ID so it's good to include both to be safe.
