Convert Column Datatype to Whole Number Datatype (Time) in Power BI

Convert Column Datatype Whole Number to Datetime in Power BI

When working with data in Power BI, it is often necessary to convert column datatypes to ensure accurate analysis and visualization. One common scenario is converting a column datatype of Whole Number to Datetime. This article will provide a detailed guide on how to accomplish this task in Power BI, covering key concepts, applications, and significance.

Why Convert Whole Number to Datetime?

Converting a Whole Number column to Datetime is essential when the data represents time-related information, such as timestamps or durations. A Whole Number column cannot be used directly for time-based calculations or visualizations. By converting it to Datetime, you can unlock the full potential of Power BI's time-handling capabilities.

Example Scenario

Consider a dataset containing timestamps represented as Whole Numbers, where each number represents the number of seconds since a specific date and time. To convert this Whole Number column to a Datetime column, you need to follow these steps:

1. Load the dataset into Power BI
2. Create a new calculated column
3. Use the DATEADD() and TIME() functions to convert the Whole Number to Datetime

Step-by-Step Guide

Follow these steps to convert a Whole Number column to Datetime:

1. Load the dataset:
   • Click "Home" > "Get Data" > "Excel" (or any other data source containing the Whole Number column)
   • Navigate to the dataset and click "Open"
   • Select the table or tables containing the Whole Number column and click "Load"
2. Create a new calculated column:
   • In the "Fields" pane, right-click the table containing the Whole Number column
   • Select "New column"
   • Enter a name for the new column (e.g., "Timestamp (Datetime)")
   • Type the following DAX formula:
     Timestamp (Datetime) = DATEADD(DateTime[Date], IntegerDivide(Table1[Whole Number], 86400), Time(Mod(Table1[Whole Number], 86400) / 3600, Mod(Mod(Table1[Whole Number], 86400), 3600) / 60, Mod(Mod(Table1[Whole Number], 86400), 60)))

     This formula assumes that the Whole Number column is named "Whole Number" and is located in a table named "Table1". The DATEADD() function is used to add the number of days to the "Date" column, and the TIME() function is used to convert the remaining seconds to a time format.

Converting a Whole Number column to Datetime in Power BI is a crucial step when working with time-related data. By following the steps outlined in this article, you can ensure accurate analysis and visualization of your data.
