5 Easy Steps To Convert Unix Timestamp To Datetime In Excel

When working with data, especially data from APIs or databases, you might encounter Unix timestamps. These are numerical representations of time, indicating the number of seconds that have elapsed since January 1, 1970. Understanding how to convert these Unix timestamps into a human-readable datetime format in Excel can significantly enhance your data analysis. Below are five easy steps that will guide you through the conversion process, along with helpful tips and common pitfalls to avoid.

Step 1: Input Your Unix Timestamp

Begin by placing your Unix timestamp into a cell in Excel. Make sure that the timestamp is formatted as a number. For instance, enter 1634061956 in cell A1. This timestamp corresponds to October 12, 2021, at 1:19:16 PM UTC.

Step 2: Convert Unix Timestamp to Excel Date

Excel dates start from January 1, 1900, which is a different epoch than Unix time. To convert your Unix timestamp to an Excel date, you can use the following formula:

=(A1/86400) + DATE(1970,1,1)

In this formula:

• A1 refers to your Unix timestamp cell.
• 86400 is the number of seconds in a day (60 seconds * 60 minutes * 24 hours).
• DATE(1970,1,1) provides the Excel equivalent of the Unix epoch start date.

Input this formula in cell B1, and you should see a number that represents the date.

Step 3: Format the Resulting Date

Now, the number in cell B1 still looks like a numeric value. You'll need to format it to make it more readable. Here's how:

1. Select cell B1.
2. Right-click and choose "Format Cells."
3. In the Format Cells window, click on "Date."
4. Choose your preferred date format (for example, "MM/DD/YYYY" or "DD/MM/YYYY") and click OK.

Your Unix timestamp should now be displayed in a human-readable format! 🎉

Step 4: Displaying Time Along with the Date

If you want to include the time in your converted value, use the following formula instead:

=(A1/86400) + DATE(1970,1,1) + TIME(0,0,0)

This formula adds the Excel time component, which defaults to midnight (00:00:00). If you wish to adjust the timezone, simply add or subtract the required hours from the TIME function.

Step 5: Copy the Formula for Other Values

If you have more Unix timestamps in subsequent rows, simply drag the fill handle (the small square at the bottom-right corner of the cell) downwards. This will copy the formula to other cells in the same column, converting all of your Unix timestamps in one go!

<table> <tr> <th>Original Timestamp (Unix)</th> <th>Converted Date & Time</th> </tr> <tr> <td>1634061956</td> <td>10/12/2021 1:19:16 PM</td> </tr> <tr> <td>1634080000</td> <td>10/12/2021 6:40:00 PM</td> </tr> <tr> <td>1634060015</td> <td>10/12/2021 1:13:35 PM</td> </tr> </table>

Common Mistakes to Avoid

1. Incorrect Cell Formatting: Ensure that your Unix timestamp is in a number format before applying formulas. If Excel treats it as text, the conversion won't work.

2. Timezone Misunderstandings: Be aware of your timezone. The Unix timestamp is in UTC. Adjust it using the TIME function if necessary.

3. Forgetting to Format Cells: Always format the resulting cell to display a date and time; otherwise, it may still show as a number.

Troubleshooting Issues

If your conversion doesn’t yield the expected results, here are some troubleshooting tips:

• Check to ensure that your Unix timestamp does not exceed the maximum value Excel can handle (which is far beyond the current date).
• Verify that all cells referenced in the formula are correct.
• If the result is displaying as #VALUE! or #NUM!, double-check your cell inputs for errors.
