Transform boring numbers into smart, professional Data visuals

Plain numbers cluttering your spreadsheet? Want to display percentages, currencies, phone numbers, or special data labels the way you require? This option is a powerful yet seldom-used feature in Microsoft Excel, to help retain control of how your treated data looks, without actually changing the values on the Excel sheet.

In this, you'll learn how to work with custom number formats to generate neat, intuitive, and professional-looking Excel reports.


🔢 What Is Custom Number Formatting in Excel?

Custom number formatting means changing how numbers, dates, and text are presented in cells, without actually altering the data that is stored there. The format codes used are applied like masks to cells, depending on your choice.

Example:

  • 1234567 can appear as $1,234,567.00 or 1.23M
  • This phone number, 9876543210, can be presented as (987) 654-3210

🛠️ How to Apply Custom Number Format in Excel

  1. Select your range of cells
  2. Right-click Format Cells -> Number tab.
  3. Choose Custom from the list.
  4. Type your format code into the Type field.

Click OK and watch your data take on the specified format!


📘 Some Popular Custom Formats

1. Currency with no decimals

$#,##0

2. Phone number format

(###) ###-####

3. Hide zero values

0;-0;;@

4. Display millions (M)

#,##0,,"M"

5. Add custom text

0" units"

Display: 150 units


✨ Bonus: Custom Date and Time Formats

  • Date: ddd, mmm dd yyyy -> Mon, Jun 23 2025
  • Time: hh:mm AM/PM

💡 Pro Tips for Custom Formatting

  • Use semicolons ( ; ) to define formats for positive, negative, zero, text
  • Colour code numbers: [Green]#,##0;[Red]-#,##0;[Black]0
  • Use "text" in quotes to add static labels
  • Use @ as a placeholder for text

  • Build visual dashboards using symbols (like arrows or percentage signs)
  • Standardise the input of numbers for reports
