# Transform

Table transformation may be as simple as using the [Select Columns](/cascade/tools/transform/selectcolumns.md) tool to retain or omit a column. However, many transform tools, offer spreadsheet-style formula entry. [Edit Columns](/cascade/tools/transform/editcolumns.md) lets you write a formula -- and get a new calculation. The [Filter](/cascade/tools/transform/filter.md) tool splits rows into True/False outputs, based on your criteria. [Pivot](/cascade/tools/transform/pivot.md) will allow you to aggregate and summarize a table by its columns.
