In this tutorial, we’ll cover how to convert an 8-digit number into a date format in Excel. By following the steps, you will make Excel understand the number as a date.

### Step 1: Open Your Excel File

Open the Excel file that contains the 8-digit numbers you want to convert.

If you don’t have an Excel file ready, create a new one and type some 8-digit numbers into a column.

### Step 2: Select the Cells

This allows you to create a custom date format that matches your 8-digit number.

Click "OK" to apply the custom format to the selected cells.

Excel will now display the 8-digit numbers as dates.

After you complete these steps, your 8-digit numbers will be converted to readable dates. Excel automatically adjusts its calculations to recognize the new data as dates, making it easier to analyze and manipulate.
