# How to add 1 in front of a number in Excel

Adding a prefix, such as “1,” in front of numbers in Excel is important because it enhances data consistency, aids in data interpretation, and facilitates sorting and filtering. It ensures uniformity and clarity in large data sets, provides additional context or information about the numbers, and allows for easier organization and analysis of the data

The provided data set is presented in a table format with three columns: “Index,” “Number,” and “Category.” It consists of random numerical values assigned to each index and categorized into different groups. This data set can be used for various analytical purposes, including studying relationships between numbers and categories or identifying trends within specific groups. Let’s have a look at the dataset.

## Method – 1 Using Ampersand Operator

In Excel, the ampersand operator is employed to merge multiple texts. In this approach, we will utilize this operator to prepend the number with a “1“. By enclosing the “1” within quotation marks, we will combine it with the number.

## Step – 1 Type the Formula

• Open your Excel sheet with the respective data.
• Syntax of the formula will be

• Now enter the following formula with respect to your data.

=”1″&B2

## Step – 2 Apply formula to the rest of the cells

• After you have written the formula, press Enter and your formula will be applied.
• Now in order to apply this formula to other cells simply drag the cursor from the corner of the cell.

## Method – 2 Using CONCATENATE function

You can add “1” in front of numbers in Excel by using the CONCATENATE function. This function allows you to combine the number you want to modify with the text string “1“, resulting in a new value where “1” is positioned at the beginning.

## Step – 1 Type the Formula

• Open your Excel sheet with the respective data.
• Now enter the following formula with respect to your data.
• =CONCATENATE(1,B2)

## Step – 2 Find values for the rest of the cells

• After you have written the formula, press Enter and your formula will be applied.
• Now in order to apply this formula to other cells simply drag the cursor from the corner of the cell to autofill.

## Method – 3 Using Format Cells Options

In Excel, the “Format Cells” feature provides a range of formatting options that allow us to change the visual appearance of data without altering the underlying values. This feature can be utilized to add “1” in front of a number without actually modifying the number itself. By selecting a suitable formatting option, such as adding a custom prefix or adjusting the number format, we can achieve the desired result of displaying the number with “1” in front while maintaining the original numerical value intact.

## Step – 1 Open the Format cells prompt

• To begin, choose the range of cells B2:B7
• Next, perform a right-click.
• Among the provided choices, opt for Format Cells
• As a result, a dialog box will open, prompting further actions.

## Step – 2 Adding one in front of the numbers.

• In the prompt, go to Custom under Category
• Then, in the box under the Type option type, 1#.
• Finally, click OK as a result, we will find a 1 added to the numbers in those cells.

## Conclusion:

In conclusion, adding “1” in front of numbers in Excel can be important for several reasons. It enhances data consistency by providing a uniform format to distinguish numbers from other types of data. It aids in data interpretation by providing additional context or information about the numbers. It also facilitates sorting and filtering operations, as the prefixed numbers can be treated as text, allowing for easier organization and analysis of the data. Moreover, the ability to add prefixes in Excel enables efficient data management and improves the overall clarity and usability of numerical information.
