7 Easy Steps To Convert Numbers To Dates In Excel

Converting numbers to dates in Excel can sometimes feel like cracking a code. For many, it’s a source of confusion as numbers often represent dates in a serial format. Whether you're managing a financial spreadsheet, project timelines, or personal records, knowing how to accurately convert these numbers can save you time and prevent errors. Let's break down the process into 7 easy steps that will have you converting numbers to dates like a pro in no time!

Why Are Numbers Used for Dates in Excel? 🤔

Excel stores dates as serial numbers, where January 1, 1900, is represented as 1. This means that the number 2 represents January 2, 1900, and so forth. This system is what makes date calculations easy in Excel. However, it can be bewildering when you're expecting to see a date but are instead confronted with a string of numbers.

Step-by-Step Guide to Convert Numbers to Dates

Here’s a simple tutorial you can follow. If you prefer visual instructions, feel free to explore other tutorials after reading this one!

Step 1: Identify the Number Format

Make sure the number you're looking at is indeed a date serial number. If it’s in a recognizable format like YYYYMMDD, you'll want to separate it into components before conversion.

Step 2: Change Cell Format to Date

1. Select the Cells: Click on the cells that contain the numbers you want to convert.
2. Open Format Cells: Right-click and choose "Format Cells," or press Ctrl + 1.
3. Choose Date Format: In the Format Cells dialog box, go to the “Number” tab, select “Date”, and choose your preferred date format. Click OK.

Step 3: Use the DATE Function

For more complex conversions, especially when dealing with date components (like year, month, and day), the DATE function is very useful.

Formula:

=DATE(year, month, day)

For instance, if you have year in A1, month in B1, and day in C1:

=DATE(A1, B1, C1)

Step 4: Text to Columns Feature

If your number is in a common text format (like YYYYMMDD), you can split the components using Text to Columns:

1. Select the Cells: Highlight the cells with date numbers.
2. Go to Data Tab: Click on “Data” in the ribbon.
3. Text to Columns: Choose “Text to Columns” and follow the wizard:
   • Choose “Fixed Width” or “Delimited” based on your number format.
   • Specify where to break the numbers (e.g., if your number is 20230115, you’d break it into 2023, 01, and 15).
   • Finish and ensure they’re all recognized as numbers.

Step 5: Use DATEVALUE Function

If your number is in a recognizable text format (like “01-15-2023”), you can convert it with DATEVALUE.

Formula:

=DATEVALUE("01-15-2023")

This function converts a date in text format to a serial number.

Step 6: Format Cells for Desired Appearance

1. Select the Cells: Click the converted cells.
2. Right-click and Choose Format Cells: Again, select “Format Cells”.
3. Select Your Date Style: Choose your preferred date display style and hit OK.

Step 7: Double Check Your Work

Always double-check that the conversion is accurate. A simple way is to use the ISNUMBER function to ensure that Excel recognizes your new date as a number.

Formula:

=ISNUMBER(A1)

If it returns TRUE, you’re good to go!

Common Mistakes to Avoid

• Forgetting to Format: Just converting doesn’t mean the format will change automatically. Always adjust formatting as needed.
• Not Handling Errors: If the conversion doesn't work, check if your number was formatted correctly in the first place.
• Assuming Date Formats Are Universal: Date formats can vary by region. Make sure to use the correct format for your locale.

Troubleshooting Common Issues

If you encounter issues while converting, here are some quick fixes:

• Unexpected Serial Number: If you see a large number instead of a date, recheck the formatting and the formula used.
• Confusing Date Formats: If your date appears incorrectly, make sure you're using the right date format (e.g., MM/DD/YYYY vs. DD/MM/YYYY).
