Concatenate fields in a table in ArcGIS Pro

Last Published: July 21, 2023


In ArcGIS Pro, it is possible to concatenate fields in a table, and display the field attributes in a new field using the Field Calculator. Concatenating fields may be necessary to merge or summarize two or more attributes into one field.


The instructions provided below describe how to concatenate two or more fields in a table, and display the combined field attributes in a new field using ArcGIS Pro. In this example, the street, city, and state fields are concatenated to display full addresses.

  1. In the Contents pane, right-click the selected layer or stand-alone table, and select the Attribute Table or Open option, depending on the data source.
  2. In the attribute table, click Add Field.
It is possible to use an existing field, but the output of this process overwrites the existing data in the field.

  2. Type the following expression, and replace !Field Name! with the name of each individual field to be concatenated from the Fields list:
!Field Name! + " " + !Field Name! + " " + !Field Name!
The double quotation marks (" ") with a space in between them add a space between the values that are being concatenated. If necessary, remove (" ") to eliminate the space between the field names.
