Understanding Power Query M's Time Functionality

Power Query M is a powerful data manipulation tool within Microsoft's Power BI and Excel platforms. It supports precise time value manipulations up to the ten-millionths of a second. However, such high granularity can significantly increase the size of data models, making operations less efficient. Removing milliseconds from time data is pivotal for simplifying data models and enhancing performance. This can be achieved through several approaches like formatting strings, rounding off the values, and utilizing mathematical remainder operations.

For those seeking to deepen their expertise in Power Query M, resources such as 'The Definitive Guide to Power Query M' are invaluable. BI Gorilla, as a platform, provides a wealth of tutorials and articles that cater to both beginners and advanced users looking to hone their skills in Power BI and Excel. By following structured methods to manage time data, users can optimize their data processes, leading to quicker analyses and more streamlined data handling in their professional roles.

People also ask

How do I remove seconds from datetime in Power Query?

To remove seconds from a datetime value in Power Query, you can use the DateTime.From function to truncate the datetime to just the date and the hour/minute components. This function omits the seconds from the output, streamlining your data for scenarios where seconds are unnecessary.

How do I remove time from Power Query?

In Power Query, if you need to remove the time from a datetime column, you can utilize the Date.From function. This function extracts just the date part of a datetime value, effectively discarding the time component. This is particularly useful when you are only interested in date data for analysis or reporting.

What is the time value in Power Query?

The time value in Power Query represents the time component of a datetime data type. This includes hours, minutes, seconds, and fractional seconds. It is essential for tasks that require precise time analysis or time-specific records. The Time.From function can be used to extract or manipulate this component directly from a datetime value.

How to input Date in Power Query?

To input a date in Power Query, you can type it directly using the standard date format (YYYY-MM-DD) or use the Date.FromText function if the date is in text format. This is crucial when manually entering date data or when working with sources that output dates as text strings.
