FIX: Import Wizard Does Not Import Spreadsheet Cells as Null

• Microsoft Visual FoxPro for Macintosh, version 3.0b
• Microsoft Visual FoxPro for Windows, versions 3.0, 3.0b

SYMPTOMS

When importing an Excel 5.0 for Macintosh spreadsheet or an Excel 7.0 for Windows 95 spreadsheet containing blank cells with the Import Wizard, the resulting fields in the new table contain zeros. This behavior occurs regardless of the value of the SET NULL command.

RESOLUTION

Issue a SET NULL ON command and use the IMPORT command. You can also use the APPEND FROM ... Type XL5 command after creating a table that supports null numeric values.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. This problem was corrected in Visual FoxPro 5.0 for Windows.
