# Overview

Processors are what grid columns run, and this section catalogs all of them. For how to add and configure a column, see [Columns and processors](/grids/columns-and-processors).

Provider processors, like the CRM and enrichment ones, need a credential. Pick one of your [connected apps](/connected-apps/overview) on the column, and if you have none for that app yet, an **Add** link takes you to connect it. Everything else, the AI, text, web, file, and QX processors, needs no credential at all.

Some processors return several values at once, held in one cell as an object. Double-click the cell to look through it, type `/` in another column to use one of its fields, or flatten a field into its own column with **Extract Field From Object**.
