### Goal Seek (another What-If Analysis Tool)

Continuing with our Excel Tutorials, in this article, I’ll take you through using Goal Seek in Microsoft Excel. The function is same as that of earlier versions of Excel as well as Excel 2010. Goal Seek is yet another What-If Analysis Tool that is extremely useful and forms an integral part of many Excel modelling exercises. Unlike data tables, which allow you to change one or more variables to find how the output varies, goal seek allows you to “set” the value of the output at a particular value and find out what value of the input variable achieves that output.

It is the greatest thing to hit Excel in 20 years. Here are some reasons why you might consider using PowerPivot: Handle incredibly large data sets.

### Excel Factor Entry 1 – Reverse PivotTable

There comes a time when you are presented with data in a cross-tabular format but your analysis requires that the data be formatted into a traditional table (or normalized) structure. The first thing you need to do is access a tool that, prior to Excel 2007, was fairly easy to reach. It has now been pushed into the background of Excel 2007 and Excel 2010; that tool is the Pivot Table and Pivot Chart Wizard.

### How to use Excel's Data Table analysis tool

All three analysis tools are what-if tools. In other words, you can see the impact of changing input values without changing the actual data. In keeping with our first two articles, "How to use Excel's Scenario Manager analysis tool" and "How to use Excel's Goal Seek analysis tool," we'll use the Data Table feature to explore possible mortgage options by evaluating several interest rates and term values. Excel's Data Table tool works similarly to Goal Seek and Scenario Manager. You can use table values to replace variables in a formula or function. In this way, you can view what-if results without changing the original formula's references.

### How to use Excel's Goal Seek analysis tool

If you ask me, Excel's what-if analysis tools are under-used. I often respond to readers with "Have you tried a data table?" Invariably, they don't know how to implement the feature—sometimes, they don't even know what a data table is.

### Connecting to Cubes and External Data with Excel in SharePoint

While many people are still unaware of it, Excel 2010 (and even previous versions) is a very powerful business intelligence client. That’s right, I said Excel. And I don’t mean the classic grab some data, do some charts and email it around sort of Excel, I mean connecting it to Analysis Services cubes and performing fast, useful data analytics on known sets of data. It can also go off and do some pretty amazing things with the Data Mining add-in, or PowerPivot, but for now I’m going to restrict myself to using core capabilities, and getting them published to SharePoint.
