Here is a way to do it with shorter formulas, but you have to be willing to use only Column C's #NUM! error to identify when to stop looking (Column D's value will repeat the previous rows value at this location).

Put =A2 in cell C2, then put this array-entered** formula in C3 and copy it down...

=SMALL(IF(A$3:A$100-A$2:A$99>1,(A$3:A$100-A$2:A$99>1)*A$3:A$100),ROW(A1))

Next, put this array-entered** formula in D2 (note, this is D2, not D3) and copy it down...

=SMALL(IF(A$3:A$100-A$2:A$99>1,(A$3:A$100-A$2:A$99>1)*A$2:A$99,LOOKUP(2,1/(A$1:A$65535""),A:A)),ROW(A1))

The top ends of the offsetted ranges (A$99 and A$100) can be any cell address that is equal to or larger than the cell address of the last date.

**Commit this formula using Ctrl+Shift+Enter, not just Enter by itself

A follow up to my previous post...

The last paragraph (right before the double-asterisk note) does not read exactly right; perhaps this is better...

The top ends of the offsetted ranges (A$2:A$99 and A$3:A$100) can be any cell addresses, still offsetted by one, that is equal to or larger than the cell address of the last date. The key to keep in mind is the the number of cells in each of the two ranges must be the same because this is an array-entered formula and, as such, the iteration process inherent in an array-entered formula requires a cell-for-cell correspondence.

Very good, both formulas are shorter!

Thank you for your contribution and explanation!

Is there a way to reverse this formula to Convert date ranges into dates in excel. For example: from 1 March 2010 - 28 February 2011 to convert that in to list from A1 to A365 starting from 1 March 2010 and A2 2 March 2010 ans so on until 28 February 2011?
