When you link to a Microsoft Office Excel spreadsheet from a Microsoft Office Access database, and the columns of the Excel spreadsheet contain more than 255 characters, you may notice that the data in the linked table appears truncated after the 255th character.
In Access, when you link to an Excel spreadsheet that contains more than 255 characters, the column of the Excel spreadsheet is mapped to the formatted Memo data type. Because Access treats the formatted Memo field as a text field that has a 255-character limit, you can view only 255 characters. However, the data is not physically truncated in the linked table.
To work around this problem, you must import the Excel spreadsheet to an Access table when the columns of the Excel spreadsheet contain more than 255 characters.
This behavior is by design.
In Access, you can set the Format property of the Text field and the Memo field to create custom formats. You can use the following special characters to set the Format property of the Text field and the Memo field:
When you link an Excel spreadsheet to an Access database, and the columns of the Excel spreadsheet contain more than 255 characters, the columns are mapped to Memo data types, and the Format property of the Memo field is set to @. Therefore, Access treats the Memo field as a text field, and you can view only 255 characters of data.
|@||Text character. Either a character or a space is required.|
|&||Text character is not required.|
|<||Force all characters to lowercase.|
|>||Force all characters to uppercase.|
However, when you import an Excel spreadsheet that has columns that contain more than 255 characters, the columns are mapped to a Memo field with no specific format. Therefore, you can view the complete data in the field.
