# Rules in Channable
In Channable, you can use rules[^1] to edit and enrich your [product data](#user-content-fn-2)[^2] to meet the requirements of your chosen channel.
### What is a rule?
Rules follow a basic logic to help you to automatically manage and modify your items: “IF the items meet X criteria, THEN do Y”.
Perhaps you have some items in your product data that are out of stock. You can use a rule to check for these items and exclude them so that they are not listed on the channel.
Or, you want to list your products on Google Shopping, but they enforce a maximum character length for product titles, and your titles are too long. You can use a rule to adjust all your product titles to meet the exact character limit.
### Conditions
Conditions are the ‘**IF**’ part of a rule. Use conditions to filter which items you want your rule to apply to.
