  2. How to label duplicates in Power Question We don’t want to eliminate the duplicates. Rather, we wish to identify them in some way.

    later. In the meantime, do the following: Click the Add Column tab.

    From the Index Column dropdown in the General group

    , select from Zero. Figure C Include an index column.

    As you can see in Figure C, Power Inquiry added an index column– a column of consecutive values that begin with 0. Must-read Windows protection Before we can recognize duplicates, we need to determine what constitutes the duplicate.

    1. irrelevant.
    2. Statistically, it isn’t difficult that the exact same employee may make two sales on

    the exact same day of the exact same value, however it’s

    not likely. In our simple data set, this is the best we can do due to the fact that there isn’t a column that distinctively recognizes each record, such as

    an invoice number. First, we

    require to produce this group: Select the Date, Worth and Worker rows by holding down Shift while you click each header. Click the Transform tab and after that click Group By in the Table group. In the resulting dialog, Power Query occupies the very first 3 dropdowns with the chosen column names. Name the column Discover Duplicates and choose Count Rows from the Operation dropdown.

  4. As you can see in Figure E
  5. , the Discover Duplicates column returns the value 2 if the record has a duplicate.

The Find Duplicates 2 column returns the term Table, which we’ll look after later on. What this question does not do is show the duplicate records. Currently, the table returns only special records, which isn’t what we desire. We want to keep all records, which is an easy task: Click the Expand button for the Discover Duplicates 2 column.

  • duplicates with the worth 2 in the Discover Duplicates column and shows all duplicates.

    the right

    Merely resort the Index column by clicking the Index column’s dropdown and picking Sort Ascending. You can get rid of the Index column, however I’ll leave it.

    a fast and easy action. On the House tab, click Close and Load in the Close group. Then click Close and Load from the resulting dropdown. Power Query creates a brand-new sheet based on the Table’s name, which in this case is TableSales, as displayed in Figure H. Figure H Load the data into Excel. Once the data is back in Excel, you can utilize it the way you would any other information in Excel. You may want to add a conditional format that highlights the duplicates based upon the Find Duplicates values of 1 and 2.
