How To Fix Dates In Excel Showing As Numbers: A Comprehensive Guide

If you've ever found yourself puzzled by dates in Excel displaying as mere numbers, you're not alone. This common issue can throw a wrench in your data analysis, making reports look unprofessional and calculations tricky. In this guide, we’ll explore how to fix this problem effectively, including helpful tips, advanced techniques, and ways to troubleshoot issues you may encounter.

Understanding Date Formats in Excel

Before diving into the solutions, it’s essential to grasp why Excel sometimes shows dates as numbers. Excel handles dates as serial numbers, counting the days from a specific starting date, known as the "epoch date" (January 1, 1900, for Windows). For example, January 1, 2021, is represented as 44,251. When you enter a date but it doesn’t fit Excel’s criteria or is formatted incorrectly, it might show up as a number instead.

Common Reasons Why Dates Show as Numbers:

• Improper Formatting: The cell format is set to "General" or "Number" instead of "Date."
• Text Entry: Dates entered as text won't convert correctly.
• Regional Settings: Your computer's regional settings might not align with the date format being used.

Step-by-Step Solutions

Let’s walk through some practical steps to resolve these issues.

Step 1: Changing Cell Format to Date

1. Select the Cells: Highlight the range of cells displaying the numbers.

2. Right-click and Format Cells: Right-click and choose “Format Cells” from the context menu.

3. Choose Date Format: Under the “Number” tab, select “Date” and pick your preferred date format.

4. Click OK: Confirm your selection by clicking OK.

Example of Changing Date Format

Important Note: Make sure that the data entered is indeed a date. If you simply format a number to look like a date, Excel won’t recognize it as a valid date.

Step 2: Using Text to Columns

If dates are still showing as numbers, you can use the Text to Columns feature to convert them.

1. Select the Cells: Highlight the range of problematic cells.

2. Go to Data Tab: Navigate to the “Data” tab on the Ribbon.

3. Text to Columns: Click on “Text to Columns.”

4. Choose Delimited or Fixed Width: For most cases, choose "Delimited" and click Next.

5. Select Delimiters: Ensure that no delimiters are selected, then click Next.

6. Set Column Data Format: Choose “Date” and select the appropriate date format (MDY, DMY, etc.).

7. Finish: Click Finish, and your dates should now display correctly.

Step 3: Checking for Text Entries

Sometimes, the issue arises when dates are entered as text.

• Check for Apostrophes: Look for any apostrophes (‘) at the beginning of the date. These indicate that Excel sees the entry as text. Remove the apostrophe and reformat the cell.

Step 4: Regional Settings

Your Excel might be set to a regional format that doesn’t match how you’re entering dates.

1. Check Windows Settings: Go to Control Panel > Region and Language.

2. Adjust Formats: Change the formats under the "Format" tab to match your date input style (e.g., MM/DD/YYYY or DD/MM/YYYY).

Troubleshooting Common Mistakes

Even with careful input and formatting, mistakes can happen. Here are some common mistakes to avoid and tips for troubleshooting.

• Entering Dates Incorrectly: Always check your input format.
• Confusing Serial Numbers for Dates: If you see a long number, remember it could represent a date; try changing the format.
• Not Updating the Format: After entering data, ensure you follow up with the formatting steps to see the changes.
