Abbreviate Number: Key Excel Tricks
Method 1: Create a Custom Format Code
Follow the steps below to create a custom code in Excel:
STEP 1: Select the cell or range of cells that require formatting.

STEP 2: Go to the Home tab and select More Number Formats from the dropdown.

STEP 3: In the Number tab, select Custom.

STEP 4: Type a custom format. For example:
Use #,, “Million” to convert 1000,000 into 1 Million.
This custom format will be saved in the worksheet and can be used later as well.
However, when we are working on a new workbook, we will have to copy the custom format into it.
Method 2: Use Formulas
You can use a combination of IF and TEXT to create a formula to abbreviate a number:
Explanation:
- A2>=1000000000: Checks if the number is greater than billions.
- TEXT(A2/1000000000, “0.0”) & “B”: Converts billions into abbreviated text like #.#B
- A2>=1000000: Checks if the number is greater than millions.
- TEXT(A2/1000000, “0.0”) & “M”: Converts millions into abbreviated text like #.#M
- A2>=1000: Checks if the number is greater than 1000.
- TEXT(A2/1000, “0.0”) & “K”: Converts thousands into abbreviated text like #.#K
- If all these conditions are false, then the original number will be displayed.
Method 3: Using Conditional Formatting
You can use Conditional Formatting to abbreviate the number and keep the underlying value the same. Follow the steps below:
Select the range and go to Home > Conditional Formatting > New Rule.
Select Use a formula to determine which cells to format.
Use formulas like:
=ABS(A1)>=1000000→ Apply formatting with an “M” suffix.=ABS(A1)>=1000000000→ Apply formatting with a “B” suffix.
Make sure to apply the formulas in the correct order, and your result will look like this:
This method keeps the numeric value intact for calculation and only changes the display.
Method 4: TOROW function
You can use the combination of dynamic arrays and the TOROW function to abbreviate numbers in Excel.
Tips & Tricks
Add Suffix

Truncating Numbers
Truncating a number is useful when you want to make the numbers look clean, but not change the underlying value. You can achieve this by using a custom format in Excel.
For example: Use format #,”K” to change 117943 to 118K
This format can be used when creating dahsboard sor reports to display numbers in a clean format. The number will maintain its integrity, and the results are precise.
