Insert missing dates

**jmiller7** · 01-19-2011, 01:34 PM

I have a set of dates from 1998-2005 but some of the days are missing.Does anyone know how to set up something in excel to find the missing dates and insert rows? Thanks

If your dates are sequential and in column A, in a helper column starting with row 2, put in this formula =if (A1+1=A2,"","Missing Date") and copy it down.

I have a database with daily average transactions from 1998-2005. Some of the days are mssing from the database. I want to create a formula that will find the missing days and insert a row. Does anyone know how to do this. Thanks.My database looks like this

Invoice Date Average Daily Price
1/1 45
1/2 48
1/3 50
1/5 45
1/6 46

I would like to enter arow for 1/4 using a formula.

With your posted data in cells A1:B6, with the dates starting in A2...

This regular formula won't insert rows (no formula can do that), but it will list the missing dates:

Copy that formula down until it returns #NUM! errors.

using your posted data, the formula returns the missing date: 01/04/2011

Is that something you can work with?
