# Add Leading Zeros to a Sequence in Google Sheets

In Google Sheets, it is possible to add leading zeros to a number or generate a sequence of numbers with leading zeros. Leading zeros are digits that are added to the beginning of a number to make it a certain number of digits long. For example, if you want to add leading zeros to the number “1” so that it becomes four digits long, you can add three leading zeros, resulting in the number “0001”. This can be useful if you want to maintain a consistent number of digits for a series of numbers or if you need to format numbers for a specific purpose. In this tutorial, we will show you how to add leading zeros to a number or generate a sequence of numbers with leading zeros in Google Sheets.

## 1. Add Leading Zeros with the PAUSE DROP Function

First, you can use the apostrophe add leading zeros to a number. To do this, you can type ‘ (apostrophe) in a cell, where A1 is the cell containing the number you want to add leading zeros to and 4 is the total number of digits you want the resulting number to have (including the leading zeros). This function will add leading zeros to the number in A1 until it reaches the desired number of digits.

## 2. Add Leading Zeros with the CONCATENATE Function

Alternatively, you can use the CONCATENATE function to add leading zeros to a number. To do this, you can type =CONCATENATE(“0000”, A1) in a cell, where A1 is the cell containing the number you want to add leading zeros to. This function will add four leading zeros to the number in A1. You can change the number of leading zeros by adjusting the number of zeros in the string of characters.

## 3. Generate a Number Sequence with the SEQUENCE Function

To generate a sequence of numbers with leading zeros, you can use the SEQUENCE function. To do this, you can type =SEQUENCE(10, 1, 1, 1) in a cell, where 10 is the number of rows you want to generate, 1 is the starting value, and 1 is the increment value. This function will generate a sequence of 10 numbers starting at 1 and increasing by 1 for each subsequent number.

## 4. Generate a Number Sequence with Leading Zeros and the SEQUENCE and CONCATENATE Functions

To combine the SEQUENCE function with the CONCATENATE function to generate a sequence of numbers with leading zeros, you can type =CONCATENATE(“0000”, SEQUENCE(10, 1, 1, 1)) in a cell. This will generate a sequence of 10 numbers with leading zeros, starting at 0001 and increasing by 1 for each subsequent number. You can adjust the number of leading zeros by changing the number of zeros in the string of characters.

## 5. Fill a Range of Cells with the Resulting Numbers

To fill a range of cells with the resulting numbers, you can select the cell with the formula and drag the fill handle (the small square in the bottom-right corner of the cell) to the desired range of cells. The formula will be automatically adjusted for each cell in the range.

## 6. Adjust the Starting Value and Increment Value in the SEQUENCE Function

If you want to change the starting value or the increment value for the sequence, you can simply adjust the corresponding values in the SEQUENCE function. For example, to start the sequence at 10 and increase by 2 for each subsequent number, you can use the formula =CONCATENATE(“0000”, SEQUENCE(10, 10, 2, 1)).
