What does “blacklisting” mean? Is blacklisting columns dangerous?
This is very safe, blacklisting means that our spreadsheet editor will ignore those fields. But they will continue to exist in your database and they will appear in the regular editor as usual. You just won’t see those columns in our spreadsheet editor.
To do that, go to Settings > Advanced Settings > Solution to weird errors > Blacklist these columns > Enter the beginning of the key of the columns you don’t want to see.
For example, the plugin Yith for WooCommerce creates a lot of columns with the key yith_field1 and creates hundreds of them, in order to blacklist all those columns at once, you’d enter the word yith on the previously mentioned field and that will remove all unnecessary columns contaning that keyword.
