Quite often, I do get questions from people who have challenge of working with dataset that wasn’t correctly entered on Excel. Hence, I write this blog post to address the problem.

In the caption below, I have an Excel sheet with over four thousand records. In column H, we discovered that the dates in that column are not recognized as proper date format. The General Number formatting attest to the fact that the dates are not property entered. We want to ultimately have the values in column H to display the proper date format using Power Query.

Click OK.

In the Get & Transform Data group of the Data tab, click on From Table/Range. The data will automatically be loaded into the Power Query editor.

That’s all we need to do! In the caption below, we can see that the improper dates we saw earlier has been converted to Dates courtesy of Power Query. This is amazing!
