An exporter is a
software application
Software is a set of computer programs and associated documentation and data. This is in contrast to hardware, from which the system is built and which actually performs the work.
At the lowest programming level, executable code consists ...

A data file is a computer file which stores data to be used by a computer application or system, including input and output data. A data file usually does not contain instructions or code to be executed (that is, a computer program).

). An exporter often is not an entire program by itself, but an extension to another program, implemented as a
plug-in. When implemented in this way, the exporter converts the hosting application's native format into the desired format and writes it to the file.
For example, a
3D model
In 3D computer graphics, 3D modeling is the process of developing a mathematical coordinate-based representation of any surface of an object (inanimate or living) in three dimensions via specialized software by manipulating edges, vertices, an ...

game tools can also export from their native format into formats for other applications (such as the modeler or a paint program, such as

Exporters are important tools in the
video game industry
The video game industry encompasses the development, marketing, and monetization of video games. The industry encompasses dozens of job disciplines and thousands of jobs worldwide.

importer
An import is the receiving country in an export from the sending country. Importation and exportation are the defining financial transactions of international trade.
In international trade, the importation and exportation of goods are limited ...
. Importers and exporters are often used in conjunction with one another in many software development environments.
