# Automatic Links An automatic link can be added to any non-Noloco data source, such as Google Sheets or Airtable. It allows you to add a custom link to another table/record from an existing record and then automatically sync that value with a lookup value. For example: If you have two spreadsheets, one named `Software` and one named `Suppliers` The `Software` sheet has a `Supplier Name` column and the `Supplier` sheet has a `Name` column. But there's no link between them (because it's a spreadsheet) You can define a new Automatic link field on the `Software` table: `Supplier` Then you can make it automatically link when `Supplier Name` = `Supplier` ![Automatic link between Supplier and Supplier Name](https://319575345-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F-MifpIQWu0HCVYAt51oT%2Fuploads%2Fgit-blob-7fd09a56fa1ae6b743d6fc53c37f31494d885652%2Fimage.png?alt=media) Automatic links are bi-directional, so if you then update the linked field on a record (say the Supplier field), Noloco will automatically prefil the `Supplier Name` field in your spreadsheet with the correct value. This makes it much easier to work with, as it introduces better filters, better views and better permissions. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
