Finding the Smallest Even Value
When processing data in a worksheet, you may have a need to know what the smallest (lowest) even value in a range is. You may be able to figure it out simply by looking at the values or by sorting them, but this gets harder as the list of values gets larger or if you can't sort them for some reason. You can create either a formula or a macro to determine the value you seek.
Finding the Sum of a Sequential Integer Range
In mathematics, the sum of a range of sequential integers, starting with 1, is known as a triangular number or Gaussian Summation. Here's a simple formula you can use to determine this sum.

Want to add up all the digits in a given value? It's a bit trickier than it may at first seem.
Summing Every Fourth Cell in a Row
Need to sum a series of cells that fits some regular pattern? Here are several ways that you can get the summation that you need.
Summing Only Positive Values
If you have a series of values and you want to get a total of just the values that meet a specific criteria, then you need to become acquainted with the SUMIF function. This tip shows how it can be used to sum just the positive values in a list.

Given a range of cells, you may at some time want to calculate the sum of only the largest values in that range. Here is an examination of various ways you can get the sum you need.
Summing When the First Character Matches a Value
Summing data is a common need in Excel. Summing lots of data based on a condition that needs to be met can be a bit more challenging, but it can be done. Here's one specific example.
Throwing Out the Lowest Score
Want to add up a bunch of scores, without including the lowest one in the bunch? You can make a small change to your formula to get the desired result.
Totaling Across Worksheets

Using a Numeric Portion of a Cell in a Formula
If you have a mixture of numbers and letters in a cell, you may be looking for a way to access and use the numeric portion of the value. You can do it in a couple of different ways, as described in this tip.
Using Named Formulas Across Workbooks
You can use the naming capabilities of Excel to name both ranges and formulas. Accessing that named information in a workbook external to your current workbook can be a challenge. Here's how to approach the problem.
Where Is that Text?
