When you query a table that is linked to a Microsoft Excel spreadsheet, you may receive the following error message:
Numeric field overflow.
Access assigns a data type for each field of the Excel spreadsheet. This assignment is based on the data that is contained in the first eight rows. For example, if a field has a Number data type that is in the first eight rows and then has text values in some of the remaining rows, Access assigns the Number data type to the link table field. This causes Access to fail to link the records that have text data values. When you query this field, Microsoft Jet Database Engine encounters text where a number is expected. The query fails with the error message in the "Symptoms" section.
To work around this problem, you must make sure that the data values in each field of the source Excel spreadsheet are exactly the same data type. Or, if the fields of the Excel spreadsheet contains data values of a mixed data type, then format the field as Text. Use the following code to reenter the values in the cells. Then, link the Excel spreadsheet to Access. To do this, follow these steps:
Note Before you start these steps, you must backup your Excel spreadsheet.
When you import, do not link an Excel spreadsheet. This is because the Text data type has a priority in the import algorithm. For example, if the predominant data type that is based on a sampling of data is numeric, but there is at least one text value in that sample, Access imports the whole field as Text.
