If you want to use the numbers contained in a column, such as the postal code in an address, you may want to extract this numbers to a new column.


  1. Select the column from which you want to extract numbers.
  2. In the Functions panel, type Extract Number and click the result to execute the associated function.


The numbers contained in the selected column are extracted to a new column. If the numbers are written using metric prefixes, such as 1k instead of 1000, they will be extracted and written using the American standard.
