The Unix timestamp is a widely used format for representing time in programming languages and databases. However, when working with Unix timestamps in Excel, it can be challenging to convert them into a readable date and time format. In this article, we will explore five ways to convert Unix timestamps in Excel, making it easier to work with this format in your spreadsheets.
Understanding Unix Timestamps
Before we dive into the conversion methods, it's essential to understand what Unix timestamps are. A Unix timestamp represents the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC. This format is widely used in programming languages, such as Java, Python, and JavaScript, as well as in databases like MySQL and PostgreSQL.
Why Convert Unix Timestamps in Excel?
Converting Unix timestamps in Excel is crucial when working with data that contains timestamps in this format. By converting these timestamps, you can perform various operations, such as data analysis, filtering, and visualization, more efficiently.
Method 1: Using the CONVERT Function
One of the simplest ways to convert a Unix timestamp in Excel is by using the CONVERT function. This function converts a value from one unit to another. To use the CONVERT function, follow these steps:
- Select the cell that contains the Unix timestamp.
- Go to the formula bar and type
=CONVERT(A1,"s","d"), where A1 is the cell containing the Unix timestamp. - Press Enter to apply the formula.
The CONVERT function converts the Unix timestamp from seconds to days, which can then be formatted as a date and time.
Method 2: Using the DATE Function
Another way to convert a Unix timestamp in Excel is by using the DATE function. This function returns a date value from a given year, month, and day. To use the DATE function, follow these steps:
- Select the cell that contains the Unix timestamp.
- Go to the formula bar and type
=DATE(1970,1,1)+A1/86400, where A1 is the cell containing the Unix timestamp. - Press Enter to apply the formula.
The DATE function adds the Unix timestamp to the base date of January 1, 1970, divided by the number of seconds in a day (86400).
Method 3: Using VBA Macros
If you prefer to use VBA macros, you can create a custom function to convert Unix timestamps in Excel. To create a VBA macro, follow these steps:
- Press Alt + F11 to open the VBA Editor.
- In the VBA Editor, go to Insert > Module to create a new module.
- Paste the following code:
Function UnixToDateTime(unixTimestamp As Long) As Date: UnixToDateTime = DateAdd("s", unixTimestamp, "1970-01-01 00:00:00"): End Function - Save the module by clicking File > Save.
To use the VBA macro, follow these steps:
- Select the cell that contains the Unix timestamp.
- Go to the formula bar and type
=UnixToDateTime(A1), where A1 is the cell containing the Unix timestamp. - Press Enter to apply the formula.
The VBA macro converts the Unix timestamp to a date and time value.
Method 4: Using Power Query
If you are using Excel 2016 or later, you can use Power Query to convert Unix timestamps. Power Query is a powerful data manipulation tool that allows you to transform and load data from various sources. To use Power Query, follow these steps:
- Select the cell that contains the Unix timestamp.
- Go to the Data tab and click on From Other Sources > Blank Query.
- In the Power Query Editor, go to Add Column > Custom Column.
- In the Custom Column formula bar, type
=Date.From(#datetime(1970, 1, 1, 0, 0, 0)) + #duration(A1)and click OK. - Click Load & Close to load the data into Excel.
The Power Query formula converts the Unix timestamp to a date and time value.
Method 5: Using a Third-Party Add-In
If you prefer to use a third-party add-in, there are several options available that can help you convert Unix timestamps in Excel. One popular add-in is the "Unix Timestamp Converter" add-in, which can be downloaded from the Microsoft Store.
To use the add-in, follow these steps:
- Download and install the add-in from the Microsoft Store.
- Select the cell that contains the Unix timestamp.
- Go to the formula bar and type
=UnixTimestampConverter(A1)and press Enter.
The add-in converts the Unix timestamp to a date and time value.
