Reorder and/or Remove Columns
Splitting Cells into Columns
Combining Cell Values/ Concatenate
value + cells[‘Column’].value
where "value" is the current column, and 'column' is the name of the column whose values you would like to combine. Note, nothing will happen if the column name is not exact.
You can also add additional syntax using a plus sign, such as,
value + "-" + cells[‘Column’].value
to add, in this example, a dash between the content being combined.
OpenRefine also can support splitting rows into columns, and splitting cells into columns or rows using the dropdown menu for the column.
