# Simple Exports

As mentioned in the [Overview](../overview.md) section, **simple exports** are
functions defined in fmu-dataio that export **standard results**. A **standard
result** is exported data that adheres to the FMU data standard.

## Key Features

- Simple to use functions
- Strict input arguments and output data
- Validation of data at export
- Used for non-FMU services like REP, DynaGeo, and more

## Current Standard Results

Below are the currently supported standard results. These pages provide
detailed information on where, how, and when to use the export function.

```{admonition} In Development
:class: important
Standard results are still in development. This list will continue to grow
over time as new standard results are added. For exporting other types of
data, check out the [Custom Exports](../custom_exports/index.md) section.

## When to use

Simple exports are the **recommended** way to export data. Simple exports
provide consistency and data quality guarantees so that this data can be used
in a uniform manner for visualization, aggregation, analysis, and more.

Simple exports **do not** limit your ability to export data in a customized,
non-standard way. Standard results from simple exports can be seen as results
from FMU as a system, rather than results from a specific FMU workflow.

This means that the best practice is to implement simple exports to maximize
the utility of your exported data. For more local and personalized needs you
can use [Custom exports](../custom_exports/index.md) in addition to them.


## Custom Exports

The number of standard results is still growing and many types of data do not
have a simple exporter yet. For all other data, you will need to use [Custom
Exports](../custom_exports/index.md).
