RE: Deduping data

Hi Liz,

Thank you for your question.

There is no specific way of doing this in Excel 2003. However there is a method using Autofilter that you could try.

I have included a hyperlink to a Microsoft site explaining the Autofilter method:

http://office.microsoft.com/en-us/excel/HA010346261033.aspx

There are also formulas you can try such as:

=IF(AND(B3=B4,C3=C4),"delete","don't delete")

Here is a link to some other formulas you could try:

I hope this answers your question.

Excel tip:

Conditional formatting for cells that return text , not picked up by Go to command

If you have tried to format all cells containing text even those that display text as a result of a formula you may have had difficulty. As Go to command with constant selected does not pick up formulas that result in text.

Then try this. Select the range the formula cells appear in on your sheet. Format, select Conditional Formatting menu. In the dialog box under Condition 1, select "Formula Is" from drop down. Next to it in the Formula Box, enter the formula =Istext(A1. Click Format button , choose desired formatting settings and click OK. To go ahead and apply the conditional formatting click OK to accept
