Excel vs Google Sheets

When writing an article about Excel and its importance in data analysis, it is almost impossible to do it without mentioning Google Sheets. Though Excel was built long before Google Sheets, these two are now almost comparable in terms of features and popularity. So what are the major difference between Excel and Google sheets? Let’s get to know.

  • Functions: Excel has an edge over Google Sheets in terms of the number of functions it has. Large number of formulas make Excel the popular choice till now, but it can change in the recent future as Google is adding new functions aggressively over the last years.
  • Price: Microsoft Office 365 costs $8.25 per month. While you can use Google Sheets for free. However, there is a business subscription that costs $5 per month.
  • Data Analysis & Visualization: If you are planning to mostly perform data analytics, Excel is surely a superior option given its large array of functions as well as built-in charts and visualization options. Google Sheets, on the other hand, has fewer number of formulas and only manual visualization capability.

Most Important Excel Functions for Data Analysis

Now that we know the way we should use excel for data analysis, let’s learn the most important functions that are a must for data analysts. If you are a beginner, these are the formulas that you will be working with the most.

1. CONCATENATE

We’re starting with one of the most important functions, CONCATENATE. This handy function lets you combine the data of multiple cells into one single cell. Once you start your journey as a professional data analyst, you’ll realize the tur importance of this function.

Also, below is an example of how it works.

CONCATENATE

Formula: =CONCATENATE(cell1, cell2)

2. LEN

LEN is another function that is highly used in data analysis. We often need to calculate the number of characters on a cell. For example, if you analysis a product dataset for an eCommerce business, you’ll find lots of different SKUs. If you can display the number of characters, you can easily get to know it. Apart from that, you might need to set a word limit for a cell, which is quite easy with this function.

LEN

Formula: =LEN(cell)

3. SORT

SORT is one of the self-explanatory features that say it all through its name. This is not only a necessary feature but also a lifesaver. Imagine finding a certain value from thousands of disordered data? It could’ve been a nightmare for a data analyst had there not been this function.

With SORT, you can just arrange your data by highest or lowest value, and easily find out the one you need. An ordered list also makes life easy for a data analyst in many ways.

Here’s how you can use this feature.

4. FILTER

FILTER is another super handy feature from excel. It is used when you need to show that contains one or more specific terms. When you have thousands of data to analyze, this is another feature that will help immensely.

5. VLOOKUP

Ah, the VLOOKUP! Even if you haven’t worked as a data analyst, you must know this function if you did even some small task-completion with excel. It is considered as one of the most recognized excel function.

Using VLOOKUP, you can easily find data associated with a value that the user chooses. This feature has multiple impressive applications. You can search within a single table or multiple tables.

For example, you have Name and Employee ID in one table and Name and Salary in another, you can easily add them together using VLOOKUP.

Let’s see how VLOOKUP works.

VLOOKUP formula consists of 4 different parameters, LOOKUP_VALUE, TABLE_ARRAY, COL_INDEX_NUM, [RANGE_LOOKUP

  • LOOKUP VALUE is the value you want to look for.
  • TABLE ARRAY is the table where you want the function to look.
  • INDEX NUM is the column number of the information you need.
  • RANGE LOOKUP is used to specify the type of lookup.

Here’s how we started the VLOOKUP. We specified the value we want to look at, which is Johnny in our case. Then we selected the cell where the value Johnny is.

6. LEFT / RIGHT

Remember what CONCATENATE does? Well, the LEFT/RIGHT function does the opposite. With these two functions, you can extract data extract specific text/number from a cell. While the LEFT formula extracts these data from the beginning part, the RIGHT formula does it from the end.

8. IF

IF function helps automate decision making. This makes it a very important function for data analysis.

With the IF function, you can make excel do a specific task or show a result based on the outcome of another operation. Let’s see an example of what IF does and how we can automate a decision using this function.

We want to if the birth year is 1996 or not, so we selected ==1996 in the first parameter, and then set the formula to show True if the value is true and False if the value is false.

Let’s say you have many different numbers, but you want to get the sum of a specific number (i.e. 50) of that table. This function will find how many times the number is present on that table and do a sum.

Here’s how it works.

Now we can find the sum of the values that are exactly 1995. Here is the result.

10. COUNTIF

COUNTIF function is almost like the SUMIF. But unlike SUMIF, it does not actually sum-up all the number that matches your criteria. COUNTIF calculates and shows you how many times your desired data is present on the sheet.

The operation of COUNTIF is very straightforward and goes like below.
