Which MIME types are related to file extension ".jsonc"?
The .jsonc file extension is associated with 1 MIME types:
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .jsonc Files
JSONC files are text files that hold JSON data with comments. They use the MIME type text/javascript even though they are not pure JavaScript files.
They are mainly used in development settings where configuration files need inline explanations. Comments allow developers to describe settings without affecting data parsing.
- Main use case: Storing configuration data (for example, in editors like Visual Studio Code).
- Other uses: Enhancing JSON files with human-readable notes for clarity during development.
- Technical detail: They adopt the MIME type text/javascript to accommodate JavaScript-like structures while allowing comments.
- Software support: Opened and edited by text editors like Visual Studio Code, Sublime Text, and Notepad++.
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 JSONC file?
JSONC stands for "JSON with Comments." It is a variation of the standard JSON format that allows developers to include C-style comments (using // for single lines or /* */ for blocks) to explain configuration settings, which is not permitted in strict JSON files.
How do I open and edit a .jsonc file?
You can open .jsonc files using any text editor or source code editor. Visual Studio Code is the most popular choice as it uses this format natively for its settings, but Sublime Text, Atom, and Notepad++ also handle them well with appropriate syntax highlighting.
Why does my JSON parser return an error when reading a .jsonc file?
Standard JSON parsers, such as JSON.parse() in JavaScript, consider comments to be syntax errors. To read a .jsonc file programmatically, you must use a specialized parser (like the jsonc-parser library) or strip the comments out before passing the data to a standard JSON parser.
What is the difference between .json and .jsonc?
The primary difference is that .json is a strict data interchange format that forbids comments and trailing commas to ensure universal compatibility. In contrast, .jsonc is designed for human readability and configuration, allowing comments to document specific settings.
How can I convert a .jsonc file to standard .json?
To convert the file, you simply need to remove all comments and ensure there are no trailing commas. Many code editors have plugins to "Minify JSON," or you can use online tools and command-line utilities (like strip-json-comments) to sanitize the content for standard usage.
What MIME type is used for JSONC files?
JSONC files often use the MIME type text/javascript because the comment syntax (// and /* */) is borrowed from JavaScript. While they are structurally similar to application/json, the presence of comments technically makes them invalid JSON. You can look up more type definitions at mime-type.com.
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.
