 ### Exploring numeric columns
 
-When a table is imported into OpenRefine, all columns are treated as having text values. We saw earlier how we can sort column values as numbers, but this does not change the cells in a column from text to numbers. Rather, this interprets the values as numbers for the purposes of sorting but keeps the underlying data type as is. We can, however, transform columns to other data types (e.g. number or date) using the `Edit cells` > `Common transforms` feature. Here we will experiment changing columns to numbers and see what additional capabilities that grants us.
