Inserting numbers or serial numbers in Google Sheets is very simple and easy. But there are various ways to do it. And some methods are useful depending on the nature of the data. This article gives you a comprehensive idea of how to insert numbers in Google Sheets in usual cases as well as in some special cases depending on the data you are working on.

## A Sample of Practice Spreadsheet

You can download the spreadsheets from the link below. The spreadsheets contain a dataset we use here. After downloading you can practice on your own as we demonstrate here.

## 7 Easy Ways to Insert Serial Numbers in Google Sheets

There are various ways of inserting numbers in Google Sheets. We are going to discuss seven different methods of how to insert numbers using the following dataset.

### 1. Double-Clicking Fill Handle Icon

The easiest and quickest way to insert serial numbers in Google Sheets is by double-clicking on the fill handle tool. But we need to insert the first two numbers of the serial manually.

**📌 Steps:**

- First of all, we insert the first two serials manually in the first two cells like in the image below.

- Then we select the first two serial numbers that we already inserted and
**double-click**on the fill handle icon as indicated.

- As a result, all the rows of the
**Serial No**column are filled with their corresponding serial number.

### 2. Dragging Down the Fill Handle

In this method, we are going to employ the previous method but in a different way. Instead of double-clicking, we drag down the fill handle to insert serial numbers in Google Sheets.

**📌 Steps:**

- At the very beginning, we insert the first two serials manually in the first two cells like in the image below.

- Next, we select the first two serial numbers that we already inserted and drag down the fill handle as follows.

- Consequently, we get the
**Serial No**for the rows other than the first two rows.

### 3. Adding One to the Previous Number

The next way to insert serial numbers in Google Sheets involves the use of **the** **SUM function**.

**📌 Steps:**

- Firstly, we select cell
**B5**. - After that, we write down the following formula in the formula bar.

`=SUM(B4,1)`

- Hence, we get the first serial number in the selected cell.
- Next, we use the fill handle tool to get the serial number of the subsequent rows.

- Once we complete the fill handle operation, we get the following result.

### 4. Using the ROW Function

**The ROW function** is another useful technique for inserting serial numbers in Google Sheets. In this method, we are going to demonstrate how to insert serial numbers with a few easy steps described below.

**📌 Steps:**

- At first, we select cell
**B5**. - Afterward, we insert the formula below in the formula bar.

`=ROW()-ROW($B$4)`

** **

- Here we are subtracting the row number of cell
**B4**from the first row of our data because our first data is in the**5th**row of the spreadsheet. - Thus we get the serial number in the selected cell.
- Then we drag down the fill handle to fill the subsequent rows with the corresponding serial number.

- Finally, we get the desired serial number inserted as follows.

### 5. Applying COUNTA Function

We can apply **the COUNTA function **as well to insert serial numbers in Google Sheets. For this, we need to follow the steps described below.

**📌 Steps:**

- Initially, we select cell
**B5**as earlier. - Next, we insert the formula below in the formula bar.

`=COUNTA($C$5:C5)`

- As a result, we get the first serial in the selected cell.
- Afterward, we drag down the fill handle tool to get all the serial numbers.

** **

- After completing the fill handle task we get the following result.

### 6. Utilizing ARRAYFORMULA Function

The next but not the last way of inserting numbers in Google Sheets involves the utilization of **the ARRAYFORMULA function**. We can get the serial number for the whole dataset just by writing the formula in the formula bar.

**📌 Steps:**

- First of all, we select cell
**B5**. - Next, we write down the following formula in the formula bar.

`=ARRAYFORMULA(IF(C5:C <> "",ROW(B5:B )-4,""))`

__Formula Breakdown__

**ROW(B5:B )-4**

The** ROW **function counts the row number for each of **column B **from cell **B5**.

**Result: **1

**IF(C5:C <> “”,ROW(B5:B )-4,””)**

**The IF function **returns blank if the corresponding cell of **Column C** is blank.

**Result: **1

**ARRAYFORMULA(IF(C5:C <> “”,ROW(B5:B )-4,””))**

Finally, the **ARRAYFORMULA** dynamically fills all the rows with the given formula written inside of it.

**Result: **1

- Finally, we press
**Enter**and get the following result.

### 7. Implementing SEQUENCE Function

The last method we are going to discuss to insert numbers in Google Sheets is the implementation of **the SEQUENCE function**.

**📌 Steps:**

- Initially, we select cell
**B5**as earlier. - Next, we insert the formula below in the formula bar.

`=SEQUENCE(COUNTA(C5:C))`

- Lastly, pressing the
**Enter**key gives us the following result.

## How to Insert Numbers with Blank Rows in Google Sheets

Now, let’s say there is no data for some rows in the middle of our dataset and we still want to insert serial numbers using the **COUNTA** function. We can easily do that. However, we need a couple of helper functions along with the **COUNTA** function.

Say, we have some blank rows in our dataset that were previously filled. Now we want to insert serial numbers in the dataset below. Follow the steps below to do this.

**📌 Steps:**

- Here we select cell
**B5**as usual. - Then we insert the formula below in the formula bar.

`=IF(ISBLANK(C5),"",COUNTA($C$5:C5))`

__Formula Breakdown__

**COUNTA($C$5:C5)**

The **COUNTA **function counts the number of cells within the range **$C$5:C5**.

**Result: **1

**ISBLANK(C5)**

**The ISBLANK function **whether the cell **C5** within its argument is blank or not.

**Result:** FALSE

**IF(ISBLANK(C5),””,COUNTA($C$5:C5))**

The **IF **function returns the value of **COUNTA($C$5:C5) **if the given condition is false.

**Result: **1

- Consequently, we get the first serial in the selected cell.
- Later we perform the fill handle operation as indicated in the image below.

- Thus, we get the serial number in the desired rows. One important thing to notice here is that the formula avoids inserting serial numbers in the blank rows as we already mentioned.

## Things to Remember

Always remember you can’t perfectly insert serial numbers using the **ARRAYFORMULA** describe here if there are any blank rows.
