Define which values should be treated as NULL (comma-separated)

Specify values that should be converted to NULL/empty during import. This is useful when your source data contains specific strings (like "NA", "N/A", "#N/A") that should represent NULL values.

Examples:

• null,NULL,#N/A,,N/A
• NA,N/A,UNKNOWN
• #N/A

Default: null,NULL,#N/A,

Use Case: Ensure consistent NULL handling across your imported data, especially when converting from spreadsheets where various formats may represent missing values.
