Hi @laravl ,
When you extract the file, Select the checkbox 'export label instead of internal values of enumeration'. So that you can see the normal text as you seen in Status and Error reason on Administration > Channels > Quarantines > Addresses.

These numbers are enumeration values defined in resource data model structure.
To see which number corresponds to which text, go to that schema under Administration > Development > Diagnosis > Data Schema > in search menu click on 'Display all schema' and search for delivery schema (nms:delivery) > in source tab of it, you can find the enumeration for status (its number value and its label text).
Similar way, you can search for other schema and can able to see what is the label text for the numbers you see in Extract report.

For example, in Delivery resource, Status field is such example for enumeration. If you see the data model for delivery, the enumeration values are as below

For more details on data model, you can refer here
But to see the text instead of numbers in your output csv file, you can enable 'export label instead of internal values of enumeration' while exporting.
