How to Take Advantage of the Go To Special Dialog Box Options in Excel

Go To Special Options

Go To Special Options

In my opinion, the Go To Special Options Dialog Box offers some of the most useful tools in Excel!

Why?

Because,  you must…

Select Cells Before Performing an Action on these Cells

The “key” to understanding ANY MS Office or Windows Program is… You MUST select a single cell or a range of cells BEFORE you can perform an action on them – e.g. Formatting you selection, deleting your selection, editing your selection or auditing your selection.

Tips Presented in this Video Tutorial

  • Select cells with Comments – so that you can “format” these cells to make them easier to identify.
  • Select cells that contain Constant Numeric Values – so that you can easily “spot” cells that should – bu do not – contain formulas.
  • Select cells that contain Specific Types of Formulas – e.g. Text Formulas – to “audit” your formulas.
  • Find the “Last Cell” in your worksheet – the last cell that contains EITHER content OR FORMATTING – This can be an “eye-opener!” for you.
  • Select the cells that contain Data Validation – perhaps you failed to “validate” all of the cells in a range.
  • Select the cells that contain Conditional Formatting – perhaps your did not select ALL of the cells in a Range BEFORE you applied a Conditional Formatting RULE!
  • Learn how to select the “Visible Cells Only” before performing a copy and paste operation – especially helpful when copying the “collapsed cells” for an Excel Outline.

I am positive that Excel users at ANY LEVEL will be able to pick up at least one solid tip from this Video Tutorial. Please send me your comments to let me know what you learned – or what you need clarification on.

Learn About My New Extended Length Excel Video Tutorials

I have just published the first in a series of “Extended Length” – 90 Minutes – Video Tutorials, “Excel Pivot Tables to Summarize, Analyze and Present Your Data.” Follow this link to learn more about this tutorial. I have created separate versions of the tutorial for Excel 2010, 2007 and 2003.

How to Use the Solver Add-in for Excel – Part 2

Solver Parameters

Solver Parameters

This is Part 2 of my series of video tutorials where I demonstrate how to use the SOLVER Add-in Tool in Excel to produce a specific result for a formula.  Remember that SOLVER is an Add-in program that you must activate before you can use it. Watch Part 1 in this series to learn how to activate SOLVER.

In this tutorial, I work with the same data set that I used in Part 1. This time, I want to achieve a specific amount of Gross Profit Sales Dollars. First, however, I must determine what is a reasonable amount to set as the Target for Solver to return.

Use SUMPRODUCT Function in Excel

I use the SUMPRODUCT Function to quickly determine my possible Revenue, Cost of Goods Sold and Gross Profit is I sell all of the Units that I have in stock. Now, I have a reasonable Target for SOLVER to reach. SUMPRODUCT is a very efficient Function that, unfortunately, very feel Excel users – in my experience – know about. Follow this link to my Index of Excel Video Lessons to find additional tutorials for SUMPRODUCT.

Best Practice Tips for Solver

  • Work with a copy of your worksheet. This is always a good idea, and it is most important when you are beginning to learn how to work with SOLVER.
  • Write out your Goal for SOLVER.
  • Do you want SOLVER to Maximize the Formula? For example, to Maximize your potential profit?
  • Do you want SOLVER to Minimize the Formula? For example, to Minimize your costs?
  • Do you want SOLVER to return a Specific Number? If so, what is that number?
  • Determine your “Variable Cells.” SOLVER calls them the “By Changing Cells.” These are the cells that SOLVER will automatically adjust.
  • The Variable Cells must “feed int” the formula in your Target Cell – This is the key to making SOLVER work!
  • Write out your “Constraints.” These are the “real-world” conditions that you want SOLVER to operate under. This is the real power in SOLVER.
  • Do not treat the SOLVER results as “the Gospel.” SOLVER is a powerful Business Intelligence Tool. You, however, know your own business or industry. Use SOLVER as a tool to help you to make informed business decisions.

How to Use the SOLVER Tool in Excel to Produce the Optimal Result for a Formula

Key Points for SOLVER

SOLVER in Excel – Key Points

I am responding to a “flurry” of requests to produce an Excel Video Tutorial that demonstrates how to use the SOLVER TOOL in Excel. Here are the key points to remember when you want to use the SOLVER Tool:

Activate the SOLVER Tool

SOLVER is an “Add-in” tool that needs to be “activated” before you can use it. In Excel 2007 / 2010, you do this via Excel Options – Addi-Ins – Excel Options. In Excel 2003, you do this via the Tools Menu – Add-ins – Solver.

Prepare Data for Solver

In order to use the SOLVER Tool, you must:

  • Establish the “Target Cell.” This cell must contain a formula. This is the cell that you want to “optimize” by using SOLVER.
  • Determine the “By Changing” Cells. These are the cells that SOLVER will change in order to deliver the optimized result in the Target Cell. The “By Changing” cells MUST “Feed Into” the Target Cell.
  • Establish the CONSTRAINTS for SOLVER. This is the “key’ element that gives SOLVER its power. You can add as many constraints as needed. My recommendation is that you “write them out” before you start  to use the SOLVER Tool.

SOLVER is very powerful. However, you MUST “think it through” before you apply it. It will take lots of practice for you to understand how to properly set up your data to produce appropriate SOLVER results.

Functions for Executive Summary

I created this Excel Video Tutorial in response to a viewer who, in her company, is not permitted to use a Pivot Table to create a report. Unfortunately, this happens more often than you might think. Nevertheless, I promised to share my tips and advice. I think that many of this tips will help Excel users at all levels.

Tips Covered in this Video Tutorial

  • Use Advanced Filter to Extract a list of unique customer names from a range with @ 4,300 records.
  • Later in the lesson, I show you how to extract this list to a different worksheet – a tip that will save you time when preparing your reports!
  • How and why to convert a normal range of data into a TABLE in Excel 2007 / 2010 or into a LIST in Excel 2003.
  • How to create “Named Ranges” for your key data cells and to use them in your Formulas and Functions.
  • How to use the SUMIF, AVERAGEIF and COUNTIF Functions in your summary report.

Keyboard Shortcuts Used in this Tutorial

  • Ctrl + T to convert to a TABLE in Excel 2007 / Excel 2010
  • Ctrl + L to convert to a LIST in EXCEL 2003
  • Ctrl + A to open up the Function Arguments Dialog Box
  • Ctrl + Shift + F3 to open the Create Names Dialog Box
  • F3 to open the Paste Names Dialog Box

I decided that I will only make this video available on YouTube – I think that you will enjoy the clarity that you get from the High-Definition / Full Screen Mode.

How to Identify and Then Delete Duplicate Records in Excel

Identify & Delete Duplicates

Identify & Delete Duplicates

It is almost inevitable that, over time, your Excel data set will contain duplicate records. This can be costly – if the duplicate records are in your mailing list. And it can also result in errors when you count and calculate data.

Three Methods to Identify and Delete Duplicate Records

In this Excel Tutorial, I demonstrate three approaches to identify duplicate records in a data set:

  1. Circle Invalid Data – This tool works in coordination with Data Validation.
  2. Remove Duplicates – This powerful command was introduced in Excel 2007. It does not “preview” the records to be deleted, so my advice is to use this command with a copy of your data.
  3. Conditional Formatting – Greatly improved for Excel 2007 and Excel 2010. Now, you have a menu choice to apply conditional formatting to either Duplicate or Unique Records. If you are still using Excel 2003 or earlier, I show you how to write the formula needed to use Conditional Formatting to highlight duplicate records.

How to Prevent Duplicate Entries in Excel with Data Validation

Formula for Data Validation

Formula for Data Validation

Over time, it is easy for duplicate entries to creep into an Excel Data Set. In this video tutorial, I show you, step-by-step, how to apply Data Validation to a range of cells so that anyone who attempts to enter a duplicate value will be prevented from doing so.

Use a “Logical Formula” for Data Validation

In this lesson, I show you how to “customize” the COUNTIF Function in the Data Validation Dialog Box so that it returns the value of TRUE. Logical formulas return either TRUE or FALSE. You MUST use a Logical Formula in Data Validation.

What Else is Covered in this Tutorial?

  • Use Paste Special – Validation to extend Data Validation to a wider range of cells
  • Use Find – Go to Special – Validation to highlight all cells on worksheet that contain Data Validation
  • Use Circle Invalid Entries from the Data Validation menu to automatically “draw a red circle” around existing cells that contain duplicate values
  • How to quickly remove Data Validation from a Range of Cells

Related Topic – Conditional Formatting in Excel

Another way to highlight existing cells that contain duplicate values is to use Conditional Formatting. The improvements in Excel 2007 and Excel 2010 make this “a snap” because this is now a Menu Selection! In my next tutorial, I will show you how this is done in both Excel 2003 – with the COUNTIF Function – and from the new Menu Selections introduced in Excel 2007.

How to Use Criteria in Excel Functions and Filters

Criteria for Advanced Filter

Criteria for Advanced Filter

When you apply a Filter to an Excel data set, you use Criteria. In a filter, only the records that can answer “TRUE” to the criteria that you set will appear. The records that answer “FALSE” are hidden while the filter remains in place.

Logical Functions

The IF(), AND() and OR() Functions belong to a group of Logical Functions. In their function arguments, they evaluate a “Logical Test” and can perform one action is the answer is “TRUE” and a different action if “FALSE.” 

  • The AND() Function – each of the Logical Tests must be met in order to return the answer “TRUE.”
  • The OR() Function – if any condition is met, the answer that is returned is “TRUE.”
  • I frequently “Nest” an AND() Function or an OR() Function inside an IF() Function to test multiple criteria.

Advanced Filters in Excel

While many Excel users are familiar with Filtering, in my experience, I find that many people get confused when it comes to using Advanced Filters. In this video tutorial, I try to eliminate this confusion. Watch and you will learn how to:

  • Write Criteria for Advanced Filters using “AND” criteria and “OR” Criteria.
  • Copy the “Filtered Records” to another location
  • Use the Keyboard Shortcut Ctrl + Shift + L to quickly “toggle” normal filter drop-down menus on or off.
