Custom Formatting Tricks for Cells

This is one of Excel's most powerful formatting features: Custom Number Formats.

They allow you to change the appearance of values in cells without changing the values themselves, including hiding them.

How to Use It

  1. Select the cells you want to format.

  2. Press Ctrl + 1.

  3. Choose Custom from the Category list.

  4. Type or paste one of the format codes above.

  5. Click OK.

Why It's So Useful

Unlike formulas, Custom Number Formats only change how a value is displayed. The underlying number stays exactly the same.

  • Formulas still calculate correctly.

  • Charts still use the original values.

  • PivotTables still summarize accurately.

  • Your reports become much cleaner and easier to read.

Pro Tip

Custom Number Formats are one of the fastest ways to make an Excel workbook look more professional, without changing a single value.
