SYMPTOMS

When you use comparison operators or wild card characters, and then use the AutoFilter command to filter numeric data in Microsoft Excel, you may receive incorrect results.

CAUSE

Comparisons that rely on character positions (beginning, ending, containing, and/or wild cards) do not work with numeric data in Microsoft Excel.

WORKAROUND

To use these operators or wild cards to filter numeric data, convert the data to text as in the following example.

Example

The following example assumes that the numeric data is as follows:

   A1: 960632515
   A2: 960632516
   A3: 960632517
   A4: 960632518
   A5: 960632519
                

To convert the data to text, follow these steps:

1. Select column B.
2. On the Insert menu, click Columns.

3. In cell B1 (the first cell of the inserted column), enter the following formula:

         =""&A1
                           

4. Select the range B1:B5.
5. On the Edit menu, point to Fill, and then click Down.
   
   The new column contains the text representations of the numbers in column A.
6. With the same range selected (B1:B5), click Copy on the Edit menu.
7. Select cell A1.
8. On the Edit menu, click Paste Special. Select Values and click OK.
9. Select column B and click Delete on the Edit menu.

The numeric data that was in column A is in a text format and can be filtered using text filters.

To convert the data back to a numeric format, see the following article in the Microsoft Knowledge Base:

75945 How to convert text to numbers in Excel

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.

MORE INFORMATION

When you use AutoFilter, wild card characters and some comparison operators work correctly with text only. The following filters rely on character positions and do not work with numeric data:

• begins with
• does not begin with
• ends with
• does not end with
• contains
• does not contain
• *
• ?

The asterisk (*) wild card character represents the position of any series of characters, while the question mark (?) represents the position of any single character.
