About .lookml Files
LOOKML files are plain text files written with a YAML-like structure. They store code for data models and definitions in the Looker platform.
The MIME type text/x-yaml indicates that they follow YAML formatting, making them easy to read and edit.
This file type is vital for translating raw database data into actionable insights in business intelligence.
According to FilExt.com, LOOKML files are essential in configuring and maintaining analytical models.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is a LOOKML file used for?
A .lookml file contains source code used by the Looker business intelligence platform to define data models. It specifies dimensions, aggregates, and data relationships, effectively translating raw database logic into a reusable syntax. These files are typically text-based and follow a structure similar to YAML.
How do I open and edit a LOOKML file?
You can open these files in the Looker IDE directly within the web browser for the best experience, including validation and auto-completion. Alternatively, since they are plain text, you can use external code editors like Visual Studio Code (with a LookML extension) or Sublime Text.
What is the correct MIME type for LOOKML files?
While there is no specific standard MIME type registered solely for LookML, they are often treated as text/x-yaml or plain text due to their YAML-like syntax. You can learn more about the properties of this media type at text/x-yaml.
Why does the file look like YAML code?
LookML (Looker Modeling Language) was designed to be a dependency language based on YAML syntax to ensure it is structured, human-readable, and easy to learn. Because of this structure, systems often identify them using the text/x-yaml MIME type configuration.
Can I convert LOOKML files to SQL?
You do not convert the file itself; instead, the Looker platform reads the .lookml definitions and automatically generates optimized SQL queries to run against your database in real-time. The file acts as a logical blueprint for SQL generation rather than a static script.
Is it safe to delete a LOOKML file?
Deleting a .lookml file can break your data models and cause reports or dashboards in Looker to fail immediately. Always use version control (like Git) integrated within Looker to manage changes so you can revert accidental deletions.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
