In this tutorial, we will discuss 5 excel logic functions that you should understand. If you need to learn other logic or other kinds of formulas, then please see the list of tutorials here.

Logic function in excel is something that can be used to give results based on condition evaluation processes. The result usually depends on whether the condition is true or false.

## The Reason Why Excel Logic Formulas are Needed in Our Data Processing

Have you ever dealt with the data or condition evaluation process in your spreadsheet file? In data processing, the occurrence might be often. This process is usually needed when we have criteria for our data processing results. If the criteria are met, then the result will be this and if not, then the result will be that. This won’t be troublesome to do manually if the process is still needed just a little. However, if there are many, then the manual way will take a lot of time.

As an example of this evaluation need at work, let’s say we do an assessment for our company’s procurement vendors. Maybe there are some criteria that must be met to get particular scores in the assessment process. And probably, there are needs to look at the kind of data given by the vendors to do a further assessment. The two of them need data evaluation processes to give their results. If we want to do the assessment process optimally in our spreadsheet file, of course, we need to learn how to do the evaluation process correctly. If there are many vendors and assessment variables, then better if there is a semi-automatic way to do the evaluation.

For the data or condition evaluation needs based on logic, there are excel logic functions available in this software. They can be utilized as you need them. Each of them has its own use to be utilized in the data processing process.

As the first step to understand the functions, it might be good to understand the five most important ones first. They are the ones usually used for the logic condition or data evaluation process need. If you understand how to use them, you have a strong early knowledge for most evaluation process you need in excel.

## The List of the Most Important Excel Logic Functions to be Mastered

So, what are the excel logic functions that are better mastered? There are 5 excel logic functions that will be explained in the list below. Each of their titles has been given its Compute Expert tutorial link so you can directly learn it if needed.

### IF

Not only the most important among excel logic functions, but it is also the most important function generally. When you need to evaluate condition, then IF will give a result based on whether the condition is right or wrong. In using it, you should understand how to use it in phases too. Thus, the result of it can be more optimized for your needs.

### AND

In using IF, there might be a need to evaluate more than one logic condition simultaneously. If you want all the conditions to be right first to produce TRUE in your IF, then use AND. The need to evaluate more than one condition is usually found if there are some criteria for your result determination.

### OR

In evaluating more than one condition simultaneously, there is also the OR formula for a different condition. Use OR if you want that if one of the conditions is right, then it will produce TRUE. The use of AND or OR, of course, must be fitted to your needs when doing the evaluation process.

### IFERROR

Need to anticipate error? Error is sometimes found in our formula use in excel and it can harm our data processing results. If you want to give an alternative value when an error is produced, then you need to learn using IFERROR.

### ISERROR

Need to give the outcome other than your formula result if it doesn’t produce an error? Use ISERROR. Error is a condition that is usually needed to be anticipated in a spreadsheet file. With your understanding of using IFERROR and ISERROR, you have the complete ammunitions to do the anticipation.

Have you understood how to use those five excel logic functions? If you often do the evaluation process in your spreadsheet file, then learn the ones you haven’t understood immediately. The understanding might become important when you do data processing in this software again next time.
