Merge columns (Power Query)<\/h3>\n\n\n\n

Excel for Microsoft 365 Excel 2021 Excel 2019 Excel 2016 Excel 2013 Excel 2010<\/p>\n\n\n\n

In Power Query, you can merge two or more columns in your query. You can merge columns to replace them with one merged column, or create a new merged column alongside the columns that are merged. You can only merge columns of a Text <\/strong>data type. The following data is used in the examples.<\/p>\n\n\n\n

Tip <\/strong>   It’s a good idea to create a new column and keep the original columns so you can better prevent refresh errors that might happen down the road.<\/p>\n\n\n\n

\"Sample<\/figure>\n\n\n\n

Merge columns to replace existing columns<\/h2>\n\n\n\n

Merge columns to create a new column<\/h2>\n\n\n\n

You can insert a custom column into the query table and use a custom column to effectively merge two or more columns. In this case, the merged columns are still available along with the new merged column in the query table.<\/p>\n\n\n\n

In this example, we are merging OrderID <\/strong>and CustomerID <\/strong>separated by a space character.<\/p>\n\n\n\n

  1. To open a query, locate one previously loaded from the Power Query Editor, select a cell in the data, and then select Query <\/strong>> Edit<\/strong>. For more information see Create, load, or edit a query in Excel<\/a>.<\/li>
  2. Ensure that the columns that you want to merge are of Text<\/strong> data type. Select Transform <\/strong>> Change Type<\/strong> > Text<\/strong>.<\/li>
  3. Select  Add Column <\/strong>>  Custom Column<\/strong>. The Custom Column<\/strong> dialog box appears.<\/li>
  4. In the Available Columns<\/strong> list, select the first column, and then select Insert<\/strong>. You can also double-click the first column. The column is added to the Custom Column Formula<\/strong> box immediately after the equal sign (=).

    Tip <\/strong>   In the Custom Column Formula<\/strong> box, press Ctrl + Space to display columns and other formula elements.<\/li>
  5. In the Custom Column Formula<\/strong> box, enter an ampersand (&) after the first column that you inserted.

    The ampersand (&) operator is used to combine values in Power Query in the same way as in Excel.<\/li>
  6. You can specify an additional separator, for example a space character, by entering ” ” after the ampersand (&).<\/li>
  7. In the Custom Column Formula<\/strong> box, enter another ampersand (&) after the space character.<\/li>
  8. In the Available Columns<\/strong> list, select the second column, and then select Insert<\/strong>. You can also double-click the second column. 

    \"Specify<\/li>
  9. Select OK. <\/strong><\/li><\/ol>\n\n\n\n

    Result<\/strong>

    \"Custom<\/p>\n\n\n\n

    You can rename the custom column so that it is more meaningful to you. For more information, see Rename a column.<\/a><\/p>\n\n\n\n
