About .gnm Files
GNM files are spreadsheet documents created with the Gnumeric application.
They use the MIME type application/x-gnumeric to identify the file format.
- Spreadsheet Data: They store tables, text, numbers, and formulas.
- Software: Open with Gnumeric, a free spreadsheet program often found on Linux systems.
- Conversion: They can be converted to more common formats like XLS and XLSX.
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 GNM file?
A GNM file is a spreadsheet document created by Gnumeric, a free spreadsheet program that is part of the GNOME desktop environment. It stores data in rows and columns, including formulas and charts, similar to a Microsoft Excel workbook.
How do I open a GNM file?
You should use the Gnumeric application to open these files natively, which is most common on Linux systems. LibreOffice Calc is another open-source alternative that can often import and view GNM files successfully.
Can I convert a GNM file to Excel (.xlsx)?
Yes, Gnumeric has built-in support for saving files in Microsoft Excel formats. To convert, open the file in Gnumeric, go to File > Save As, and select .xlsx or .xls from the file type options.
Can I open GNM files on Windows?
Native Windows support for Gnumeric has been discontinued in recent years. To open a GNM file on Windows, it is best to convert it to a universal format like CSV or Excel using an online converter or use LibreOffice for Windows.
What is the MIME type for GNM files?
The standard MIME type is application/x-gnumeric. This media type helps systems identify the file as a Gnumeric spreadsheet; for more details on configuration, visit mime-type.com.
Why won't Microsoft Excel open my GNM file?
Microsoft Excel does not natively support the GNM file structure. You must convert the file to a compatible format, such as .xlsx or .csv, before Excel can read the data.
Is a GNM file compressed?
Yes, GNM files are typically XML data compressed with gzip to save disk space. If you rename the extension to .gz and unzip it, you can view the underlying raw XML code in a text editor.
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.
