I am reading an excel sheet using the ACE provider and certain cells contain data greater than 255 bytes. I tried changing the TypeGuessRows in the registry settings as well as
refer this link. I think this is the problem (try with Memo fields)

In Access tables, Text fields are limited to 255 characters,but Memo fields can handle 64,000 characters (about 8 pages of single-spaced text)
Nice workaround: have a look at this stack answer
