Stop validating excel source SSIS

Sorry to be vague, but this is too long to copy/paste

"SSIS package taking forever to load when you open it?"

This describes these 3 options which affect loading speed + the validation

• DelayValidation property
• ValidateExternalMetadata property
• “Work Offine” option

You can also "DelayValidation" to in several other places too per connection/task
