7 Simple Steps To Convert Epoch Time In Excel

Converting epoch time in Excel may seem daunting at first, especially if you're not familiar with how time is formatted in programming. But don't worry! By understanding a few simple steps and tips, you’ll be able to convert epoch time to a human-readable format effortlessly. Epoch time is the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC. This post will guide you through the process, share helpful tips, and highlight some common mistakes to avoid.

Step 1: Understand Epoch Time

Epoch time, also known as Unix time, is a way to track time in computing. It's simply the number of seconds passed since the beginning of the Unix epoch. In Excel, however, we often deal with dates and times in a different format, which is why conversion is necessary. 📅

Step 2: Open Your Excel Spreadsheet

Start by launching Excel and opening the spreadsheet where you have your epoch timestamps. If you don't have any epoch time in your sheet, you can simply type a few examples in a column for practice.

Step 3: Input Your Epoch Time

Make sure the epoch time is in a column and is formatted as plain numbers (not in a date format). For instance, enter 1635205600 in cell A1. This value represents a specific date and time in epoch.

Step 4: Use the Conversion Formula

In the next column (B1), you can use the following formula to convert epoch time to Excel's date and time format:

=(((A1/60)/60)/24) + DATE(1970,1,1)

This formula works by:

1. Dividing the epoch time by 60 to convert seconds to minutes.
2. Dividing that result by 60 again to convert minutes to hours.
3. Dividing by 24 to convert hours to days.
4. Adding the result to the starting date of the Unix epoch: January 1, 1970.

Step 5: Drag the Formula Down

Once you’ve written your formula in B1, click on the small square at the bottom right corner of the cell (known as the fill handle) and drag it down to fill other cells in the column if you have more epoch values in column A. Excel will adjust the formula for each respective row.

Step 6: Format the New Date/Time

After applying the formula, you will see the epoch time converted into an Excel date format. To make it readable, right-click on the cells with the converted dates, choose Format Cells, select Date from the list, and then pick your preferred date format. 🕒

Step 7: Final Touches

After you have formatted the date, you might want to adjust the width of the columns for better visibility. Simply double-click the line between the column letters to auto-fit.

<table> <tr> <th>Epoch Time</th> <th>Converted Date</th> </tr> <tr> <td>1635205600</td> <td>10/25/2021 12:00:00 AM</td> </tr> <tr> <td>1635292000</td> <td>10/26/2021 12:00:00 AM</td> </tr> </table>

Helpful Tips for Effective Conversion

• Use Helper Columns: If you have a large set of data, using helper columns can help simplify your process. You can have one column for epoch time and another for the converted time.
• Consistent Formatting: Ensure that all your epoch timestamps are in seconds and not milliseconds. If your timestamp is in milliseconds, divide it by 1000 before using the conversion formula.
• Backup Your Data: It's always a good practice to backup your original data before making any conversions or transformations.

Common Mistakes to Avoid

1. Confusing Time Zones: Epoch time is based on UTC. If you need to adjust for local time zones, remember to add or subtract the difference from UTC.
2. Using Incorrect Formats: When inputting epoch time, ensure it’s not formatted as a date in Excel. It should be plain numbers.
3. Overlooking Cell Formats: After conversion, ensure that the output cells are properly formatted as dates. If they appear as numbers, they won’t be easy to read.

Troubleshooting Tips

• If the Date Doesn’t Convert: Check if the epoch value is entered correctly and is indeed a number.
• If You See a Serial Number Instead of a Date: This usually happens when the cell format is still set to General or Number. Reformat the cells to Date.
• If the Time Appears Incorrect: Ensure that you are accounting for any time zone differences.
