How to Change Number in Excel Sheet

Mastering the Art of Number Modification in Excel

Microsoft Excel is a powerhouse when it comes to handling numerical data. Whether you’re a seasoned professional or a beginner, understanding how to change numbers in an Excel sheet is a fundamental skill that can streamline your workflow and enhance your data management capabilities. This article will guide you through various methods of altering numbers in Excel, ensuring that you can tackle any task with confidence and efficiency.

Understanding the Basics of Excel Number Formats

Before diving into the methods of changing numbers, it’s crucial to understand that Excel treats numbers not just as values but also as formats. The way a number is displayed can be altered without changing the underlying value, which is essential for accurate data representation.

Common Number Formats in Excel

Excel offers a variety of number formats, including:

General
Number
Currency
Accounting
Date
Time
Percentage
Fraction
Scientific
Text

Each format serves a specific purpose and can be applied depending on the context of the data.

Changing Number Formats in Excel

Altering the appearance of numbers in Excel is straightforward. Here’s how you can change number formats:

Using the Ribbon to Change Number Formats

The ribbon in Excel provides quick access to number formatting options:

Select the cells you want to format.
Go to the Home tab on the ribbon.
In the Number group, click on the dropdown menu to reveal a list of formats.
Choose your desired format, and Excel will apply it to the selected cells.

Custom Number Formats

If the standard formats don’t meet your needs, Excel allows you to create custom number formats:

Select the cells you wish to format.
Right-click and choose Format Cells, or press Ctrl + 1.
In the Format Cells dialog box, go to the Number tab.
Select Custom from the category list.
Type your custom format code in the Type box.
Click OK to apply the custom format.

For example, to display numbers with a “+” sign for positive numbers and a “-” sign for negative numbers, you could use the custom format code

"+#,##0;-#,##0"

Modifying Number Values in Excel

Changing the actual value of numbers in Excel can be done in several ways, depending on the task at hand.

Manual Entry

The simplest way to change a number is by manually typing in a new value:

Click on the cell containing the number you want to change.
Type the new number.
Press Enter or Tab to confirm the change.

Using Formulas to Change Numbers

Excel’s formula capabilities are vast, allowing for dynamic number changes:

Select the cell where you want the new value to appear.
Type an “=” sign to begin the formula.
Enter your formula (e.g.,
```
=A1+10
```
to add 10 to the value in cell A1).
Press Enter to execute the formula.

Incrementing Numbers with Fill Handle

The fill handle is a powerful tool for quickly changing a series of numbers:

Select the cell or range of cells with the numbers you want to increment.
Position your cursor over the bottom-right corner of the selection until it turns into a plus sign (+).
Click and drag the fill handle in the desired direction to increment the numbers.

Using Paste Special for Advanced Changes

Paste Special offers more control over how numbers are modified when pasted:

Copy the cell with the number or formula you want to use for changing other numbers.
Select the range where you want to apply the change.
Right-click and choose Paste Special.
In the Paste Special dialog, choose an operation (e.g., Add, Subtract, Multiply, Divide).
Click OK to apply the operation to the selected range.

Automating Number Changes with Excel Functions

Excel functions can automate the process of changing numbers, making repetitive tasks more efficient.

Using the ROUND Function

The ROUND function is used to change a number to a specified number of decimal places:

=ROUND(number, num_digits)

For example, to round the number in cell A1 to two decimal places, you would use:

=ROUND(A1, 2)

Applying the TEXT Function for Number Formatting

The TEXT function allows you to change the format of a number without altering its value:

=TEXT(value, format_text)

To display the number in cell A1 as currency, you might use:

=TEXT(A1, "$#,##0.00")

Utilizing the SUBSTITUTE Function for Textual Changes

If your numbers are stored as text, the SUBSTITUTE function can replace specific characters:

=SUBSTITUTE(text, old_text, new_text, [instance_num])

To change all instances of “1” to “one” in a text string in cell A1, use:

=SUBSTITUTE(A1, "1", "one")

Formatting Numbers for Different Locales

Excel can accommodate different international number formats, which is crucial for global businesses.

Changing Decimal and Thousands Separators

To change decimal and thousands separators:

Go to File > Options.
In the Excel Options dialog, select Advanced.
Under Editing options, you can set the decimal and thousands separators as needed.
