10 Easy Ways To Convert Epoch Time In Excel

Epoch time, also known as Unix time, is a system for tracking time that counts the number of seconds that have elapsed since January 1, 1970. While this format is commonly used in programming and databases, it may be less familiar to those who work with spreadsheets like Excel. Fear not! In this guide, we’ll explore ten easy ways to convert epoch time in Excel into a more human-readable format. 🎉

Understanding Epoch Time

Before diving into the methods of conversion, it's crucial to understand what epoch time is. Essentially, it represents the total seconds that have passed since the "epoch," a reference point used in timekeeping systems. For Excel users, this can sometimes pose a challenge as they often deal with date formats instead. Converting this time correctly is essential for proper data analysis.

1. Basic Conversion Using Excel Formula

To convert epoch time to standard date format, you can use a simple formula. Assuming your epoch time is in cell A1, the formula would be:

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

Explanation:

• Divide the epoch time by 86400 (the number of seconds in a day) to convert it to days.
• Add the result to the date "1/1/1970" to get the corresponding date.

2. Formatting the Result

Once you have applied the formula, you might want to format the result into a readable date format. Here’s how you can do it:

1. Right-click on the cell with your result.
2. Select "Format Cells."
3. Choose "Date" and select your preferred format.

This will change the appearance of the epoch time into a conventional date that you can understand better. 🗓️

3. Using TEXT Function for Custom Formats

If you want to customize how the date appears, the TEXT function comes in handy. You can modify the formula from above:

=TEXT(A1/86400 + DATE(1970,1,1), "mm/dd/yyyy hh:mm:ss")

This will allow you to display your date in the "MM/DD/YYYY HH:MM:SS" format.

4. Convert Milliseconds to Epoch Time

If you're dealing with milliseconds instead of seconds, you'll need to adjust your formula slightly. For instance, if your epoch time in milliseconds is in A1:

=A1/86400000 + DATE(1970,1,1)

5. Utilizing Power Query

Excel’s Power Query feature can also facilitate the conversion. Here’s how:

1. Go to "Data" > "Get Data" > "From Other Sources" > "Blank Query."
2. Open the Advanced Editor and enter the code:

   let
       Source = Excel.CurrentWorkbook(){[Name="YourTableName"]}[Content],
       AddedCustom = Table.AddColumn(Source, "ConvertedDate", each DateTime.From(1970-01-01) + Duration.From([EpochColumn] / 86400))
   in
       AddedCustom
   

This creates a new column that displays the converted date.

6. Creating a VBA Macro

For those who frequently convert epoch time, creating a VBA macro could save time. Here’s a simple macro to do this:

Function EpochToDate(EpochTime As Double) As Date
    EpochToDate = DateAdd("s", EpochTime, "1/1/1970")
End Function

1. Press ALT + F11 to open the VBA editor.
2. Insert a new module and paste the code above.
3. Close the editor and use the new function like this: =EpochToDate(A1).

7. Using Excel Online and Google Sheets

If you prefer using Excel Online or Google Sheets, the formula remains the same:

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

These applications fully support the method we discussed, ensuring you have flexibility across platforms.

8. Adjusting for Time Zones

If you need to account for time zones, simply adjust the result by adding or subtracting the appropriate number of hours. For example, to convert to UTC-5:

=(A1/86400 + DATE(1970,1,1)) - TIME(5,0,0)

9. Troubleshooting Common Issues

When converting epoch time in Excel, you might run into a few issues. Here are some common mistakes to avoid:

• Not using the correct reference for the epoch time: Ensure you are referring to the correct cell in your formula.
• Forgetting to adjust for time zones: If your data spans multiple regions, always check if you need to account for local time differences.
• Formatting issues: Ensure your result cell is formatted correctly to display date and time.

10. Useful Excel Add-ins

Lastly, if you regularly work with epoch time, consider using Excel add-ins that specialize in date conversions. They can simplify the process and enhance your productivity.
