In Power Query, there are multiple methods that you can use to concatenate values (numbers and text). And in this tutorial, we will learn to use these methods.

Below we have a list of first and last names in the columns:

Concatenate Values from Two Columns into One (Combine Columns)

You can use these steps:

  1. First, load your data into the power query editor (Data > Get Data > From Other Sources > From Table/Range.
    concatenate-values-from-two-columns
  2. Afterward, select both columns in the editor and go to Transform > Merge Columns.
    transform-and-merge-columns
  3. When you click on the “Merge Columns”, you will get a dialog box that selects the separator and the name of the new column.
    select-separator-and-new-ceolumn-name
  4. Once you select the separator and column name, click OK. And hit enter to get the new column.
    get-new-column

Now, we have a new single column with values from both columns (first and last name). While you use this method, you need to take care of a few things:

  1. Select the columns in the sequence you want to combine the values.
  2. You can enter a custom separator in the dialog box.

 Concatenate Columns by Adding a New Column

Unlike the above method that we have used, you can also use a custom column and function to combine values.

  1. Go to the Add Column > Custom Column.
    concatenate-by-adding-new-column
  2. In the dialog box, you need to write a formula.
    write-a-formula-in-dialog-box
  3. Enter the column’s name and then enter the formula we used in the below snapshot.
    first-enter-column-name-and-then-formula
  4. Finally, click OK to enter the formula and create a new combined column.
    hit-enter-to-run-formula

In this formula, we have used an ampersand to combine values from both columns with a space in between. It is like a formula that we use in Excel.

=[First]&" "&[Last]

Combining Text and Number into One Column

In Power Query, if you try to combine the text with numbers, you will get an error in the final value.

combine-text-and-number-into-one-column

In this situation, you need NumberToText function to convert the number into text.

text-function-to-convert-number-to-text

And once you click OK after entering the formula. You will get a new custom column.

Combining Values from a Single Column

If you have values in a column and want to get them in a single cell, you need to transpose them first.

combine-values-from-a-single-column

Select the column and click on “Transpose”.

select-column-then-click-transpose

Select the separator from the merge columns dialog box, enter the column name, and click OK.

select-seperator

You will get a new column with the values combined when you click OK.
