HOW TO
Microsoft Excel table data with field lengths greater than 255 characters can be imported to a file geodatabase. However, ArcMap converts these fields into a binary large object (BLOB) field type, and data converted into a BLOB type is not readable by ArcMap. This is currently a known limitation.
Note: No alternative workaround exists for versions prior to ArcMap 10.1.
The instructions below describe how to import Microsoft Excel table data with field lengths greater than 255 to a file geodatabase.
